Can I reuse my head gasket?

I changed the head gasket a few weeks ago but had to remove it today for other reasons. It's a standard metal mesh sandwhiched between the black fiberus paper stuff. When I removed it this time the black paper stuff ripped into a billion pieces and is stuck all over everything, but the metal mesh is 100% intact.



Can I reuse the metal mesh and spread gasket sealer over it to compensate for the black paper stuff or do I need to buy a new one?



OR, can I buy some sheets of gasket maker from the auto parts store and cut it to fit top and bottom of the mesh gasket, and possibly seal THAT with Permatex?



It's an older bike so I'd have to order it and that'll take about a week for it to come in and I'd like to get this bike finished.Can I reuse my head gasket?A head gasket is under a lot of pressure, Buy a new one, unless you feel like redoing the work and putting in a new one in a week.
Can I reuse my head gasket?
no not really, but you could use a cardboard type material and resaandwich it if its easy(fire retardant).i wouldnt even try if the job takes longer than 2 hrs or if you didnt need it desperately and it wasnt gonna be here for 2 weeks.
Can I reuse my head gasket?
Replace the headgasket with a new one. Do not chance it. It is not worth it. Replace it.
Once you torque the head, you squeeze the gasket out of shape. For no more than it would cost you, don't chance it, or you'll be tearing it down a third time.
No, once you tighten it and take it back off its done you have got to replace it, i would not even chance putting the old one back on
No!
Dont do it !!!
Jim,

The only head gasket that is reusable is a solid copper one. Even then it must be annealed with the %26quot;Blue wrench%26quot; before it will take. The one you have is done. Ignore the outrageously ridiculous advice I've seen here in some other posts. If you can get a replacement in copper that's the way to go.

How do you change a head gasket for a ford contour 2.0 1997?

You gotta be kidding me........tell you here.....in this little space.....sh*t'n me



get a book at the auto store.



or call a reputable person off Craigslist.com in your area.How do you change a head gasket for a ford contour 2.0 1997?The cylinder head bolts are a torque-to-yield design and cannot be reused. Be sure new cylinder head bolts are available before beginning this procedure. If the cylinder head bolts are reused, engine damage may occur.



1.Disconnect the negative battery cable.









CAUTION

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Coolant should be reused unless it is contaminated or is several years old.





2.Drain the engine coolant from the radiator and the cylinder block drain plugs.

3.Remove the intake manifold.

4.Remove the exhaust manifold.

5.Remove the camshafts and valve tappets.

6.Support the engine with a wood block between the crankshaft pulley and the front sub-frame.

7.Remove the engine support device previously installed for the timing belt cover removal.

8.Remove the right-hand engine lifting eye retaining bolt and the lifting eye.

9.Remove the support bracket from the power steering pump mounting bracket and cylinder head.

10.Remove the timing belt covers.

11.Remove the camshaft timing belt tensioner pulley.

12.Remove the thermostat housing from the rear of the cylinder head.

13.Remove the ignition coil and bracket from the cylinder head.

14.Remove the spark plugs if not already removed.

15.Remove the cylinder head retaining bolts in the reverse of the installation sequence.

16.Remove the cylinder head and gasket from the engine.

17.If the cylinder head is to be serviced, remove the left-hand engine lifting eye.





To install:



18.Clean the cylinder head and cylinder block gasket surfaces and check for flatness. Refer to the Engine Reconditioning Section for procedures.

19.Install a new cylinder head gasket onto the cylinder block. Be sure the head gasket is properly positioned on the dowels.









WARNING

Use care when positioning the cylinder head to prevent damage to the head gasket or dowels.



20.Place a light coating of engine oil onto the threads of the new cylinder head bolts and install.

21.Tighten the cylinder head bolts in sequence and in the following steps:





Tighten all bolts to 15-22 ft. lbs. (20-30 Nm)

Tighten all bolts to 30-37 ft. lbs. (40-50 Nm)

Rotate all bolts 90-120 degrees.





22.Reinstall the ignition coil bracket and the ignition coil.

23.Reinstall the water thermostat housing.

24.Reinstall the timing belt covers.

25.Reinstall the camshaft timing belt tensioner pulley and retaining bolt onto the front of the cylinder head.

26.Reinstall the support bracket to the power steering pump mounting bracket and the cylinder head.

27.Tighten the support bracket to 29-41 ft. lbs. (39-55 Nm).

28.Reinstall the right engine lifting eye to the cylinder head and the alternator mounting bracket. Tighten the retaining bolts to 30-41 ft. lbs. (41-55, Nm).

29.If removed, install the left-hand engine lifting eye to the cylinder head and tighten to 10-13 ft. lbs. (14-18 Nm).

30.Install the engine support device to the engine lifting eyes and support the engine.

31.Remove the wood block from between the sub-frame and the crankshaft pulley.

32.Reinstall the valve tappets and camshaft into their original locations.

33.Reinstall the exhaust manifold.

34.Reinstall the intake manifold.

35.Reinstall the spark plugs.









CAUTION

The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.





36.Drain the engine oil and remove the engine oil filter.









WARNING

Operating the engine without the proper amount and type of engine oil will result in severe engine damage.



37.Reinstall the drain plug and tighten to 15-21 ft. lbs. (21-28 Nm).

38.Reinstall a new engine oil filter and fill the crankcase with the proper amount and grade of oil.

39.Fill the engine cooling system.

40.Reconnect the negative battery cable.

41.Run the engine and check for oil and coolant leaks. Check for proper engine operation.
How do you change a head gasket for a ford contour 2.0 1997?
Changing a head gasket is very complex task and is a bit more than an average %26quot;do-it-yourselfer%26quot; can handle. As you can see from the first guy that answered your question, special tools and expertise are required. I have seen many cars for sale online where someone attempted to replace a head or a gasket and realized They were in over their head (no pun intended) and were just trying to sell it with the motor torn apart just to get it out of their yard. I do not intend for this to sound snooty, bit if you are asking in a discussion forum how to replace a head gasket, you probably should not be trying it. Good luck to you if you do....

How do i change the head gasket in a 1982 f-150 4.9 liter?

pull the head scrape the old gasket off and then call a mechanicHow do i change the head gasket in a 1982 f-150 4.9 liter?Fortunately for you the little 300 I-6 is a very simple motor. That being said, go to a book store or parts house and get a book on rebuilding motors, it will have info on how to do it properly. Good luck.
How do i change the head gasket in a 1982 f-150 4.9 liter?
Clean everything away from you head so you can work. Remembering what might go where .... use some masking take to mark if nessesary...... take valve covers off......Loosen manifolds off. After taking valve cover off you remove rocker arm. take out lifters and push rods setting them aside.... now remove bolds holding head on....... it will lift out with a little pursuading........ clean old gasket out..... clean up bottom of head and where they sit with steel wool....... put new gasket in. using any directions......... Put head back in place. Be very care bolting back in... use torque wrench .... find out torqe ... I don't know....remember go around and bolt it right.... little on each going like you do when changing a tire.... BE VERY CAREFUL YOU CAN WARPE THE HEAD....Thyen put lifters push rods and rocker back on...You can do it and I have done it before ....... and I am not a mechanic......

If you google this question you may find ore help .......

What you have just done on a saturday just saved you many hundred dollars....they charge about 1200.00 to 1500.00
How do i change the head gasket in a 1982 f-150 4.9 liter?
It is easy ,all the room is there.Hardest part is to lift the cylinder head out.Start with the valve cover,intake and exhaust manifold bolts.Then head bolts.
The instructions provided were basically correct. You need to get a manual so you know 1) the torque specs for each bolt and 2) the sequence to tighten the head bolts (center out in a clockwise pattern?). Lifting the head out is a bit heavy, I ruptured a disk doing mine on the 250.



Get a head rebuild kit from your parts dealer and it will have all the correct gaskets. While you have the head off, do a valve job. ream the guides and replace the seals

Head gasket!!!!!!!!!!!!!!!!!!?

hi, just need to know how hard it is to change a head gasket, and what makes it so expensive in a garage? is it the labour or parts???

a quick answer would be great thanks in advance!!!!!!!!!!!!!!Head gasket!!!!!!!!!!!!!!!!!!?mostly labour have to tear half the engine down
Head gasket!!!!!!!!!!!!!!!!!!?
Time consuming on most cars - labour is the biggy
Head gasket!!!!!!!!!!!!!!!!!!?
6 hours labour 拢180

Head skimmed and pressure tested 拢80

Gasket kit 拢80

This covers the basics only.

Varies according to the car model.
What makes it hard is the intake and exhaust system. Exhaust systems are notorious for frozen nuts and broken studs. Along with this goes having to pull ignition parts on some cars.

The cost is almost all labor.

For some one to do it themselves, it will take almost (if not more) money to buy all the tools needed.

On some cars (in-line) the job can be done on two hours, while on others (V) it can take a day (or more).

If you are having this job done by a professional, they will have connections to make sure that it is just the gasket and not a warped head or cracks.
Its a highly labour weighted job. You have to remove all the gear off the top part of the engine, ignition, filters, manifolds, drain the coolant etc. The head, camshaft or valves may need some work done to them before the gasket is replaced and the rebuild commenced. As well as putting it all back together the timing has to be set too, which can be a complex job. Its common practice to renew the oil and filters after this job
It's not so much the parts that makes it expensive. Its the time it takes,and you will need to have the head skimmed.
To replace a cylinder head gasket you need to remove both the inlet and the exhaust manifolds, timing chain or belt covers and belt/chain. Drain the coolant, remove the rocker cover, loosen all the head bolts and then remove the head.

Once the head is off ideally to should be pressure tested to see if its cracked, it should also be checked to make sure it is still straight and true. Depending on the results you may need to have the head repaired and or machined.

All the head bolt holes need to have there threads cleaned up and then you have to re-build the engine back up.

Its a lot of labour and this makes the job expensive.

Ja.
its labour that puts the price up and if the cylinder head needs engineering that also increase cost.
It depends on the car an 8 valve over head valve engine can be changed quickly about 2 to 2.5 hours because you don have to have the head skimmed and it is easy to remove.

other cars lets say a rover 16 valve over head cam is more time consuming as you have to skim the head replace the timing belt etc.



The gaskets can cost between 拢10 to 拢60.

  • How to know if its a Head Gasket Problem?

    Hi! Thanks for reading my question.

    I was thinking about buying a cheap vehicle (under $1000) and take my time learning how to change the head gasket and timing belt and later see it if all goes well.

    So looking at Craigslist, I see many people who claim that their car has a head gasket problem.. some say they run, some say they dont.

    So my question is, How do I know for sure if its a head gasket problem and that its not something worse.

    Because by my understanding, head gaskets burn due to overheating.. So the engine could have even cracked or extended in size due to it being so hott.

    Please explain! Thank youu! :)How to know if its a Head Gasket Problem?You have to do a pressure test ...You also have to use a dye to help you find out what head is bad...Usually people will try to sell the car instead of fixing it...Usually these cars are hondas or toyotas that have aluminum heads...Sometimes the head itself is bad due to over heating...So just fixing the head gasket is opening a can of worms......Instaed of a 800.00 repair it can be over 2000.00....
    How to know if its a Head Gasket Problem?
    You have nailed the issue of this one. Anytime a head gasket blows, there is overheating involved. Which in turn can cause warping and cracking of heads and blocks.



    That being said, Oftentimes, it is simply a matter of having the head machined (to get rid of any warping) buying appropriate gaskets and installing the head correctly.

    good luck.

    Can backfires really blow your head gasket?

    When I replaced the head gasket on my truck I was 180 off on the distributor and it made many back fires before I could get it running correctly now that I have it running again I am finding water in my oil which makes me red hot because thats why I busted my balls the first time to change the head gasket but could it have been because when I pulled the intake manifold off all the coolant went into the block would that be the cause of water in my oil or would it be all the back fires blew the head gasket again? Oh and also I changed the oil to try and get rid of all the water in the oil and when I took it for a 4 minute drive when I came back I saw there was still some water in the oil would it be just left overs from the old oil that had all the water in it?Can backfires really blow your head gasket?1.No backfiring won't blow a head gasket.



    2.YES, absolutely when you took the intake off, (Which has water jackets going through it), your coolant went down into the block.



    3.Did you use a non-retorquing head gasket? You know, like a Fel-Pro blue? If not, did you re-torque the heads after the engine had warmed up good? If not, you get to clean the block and heads, buy new head gasket/s, and start over.



    4.Drain all the oil, and make sure you leave the drain plug out for an hour or so. Change the filter. Replace the oil.



    5.If you don't get the intake sealed properly, you will have water going down inside the block, and the combustion chambers. Gasket compound is used in the corners where the intake gaskets meet the intake valley gaskets.



    The area on the block needs to be CLEAN! Make sure there is absolutely no garbage on the block sealing surface area. Make sure there is no garbage on the intake sealing surfaces. (Gasket scraper until you see shiny metal. NO nothing, on either block, or intake surfaces!)



    Take clean rags, and use isopropyl alcohol, and wipe these areas down. If antifreeze is left behind, it won't let gasket compound stick. Antifreeze contains lubricant. It lubricates the water pump.



    Edit:

    When torquing the head/s, did you follow the torque sequence? Did you tighten all the bolts to a certain torque, then go around the bolts again, and again?

    Example: Heads require 65 foot pounds of torque. They should be tightened down in three stages. 20lbs, then 40lbs, then the final torque of 65lbs. You MUST follow the torque pattern for THESE heads. Rule of Thumb, is to start from the center, and spiral out.



    If the intake wasn't absolutely clean, and the block surface, plus gasket goop applied in the corners, you're going to keep seeing water in the oil. If the head gasket was the re-torque kind, and you didn't re-torque it, you're going to see bubbles coming up in your radiator. Blown head gasket again!
    Can backfires really blow your head gasket?
    Backfires occur in either the intake or exhaust (and given your situation almost assuredly it was in the exhaust) so the likelihood of it causing a head gasket issue seems pretty low. If it did occur in the intake, it could I suppose have damaged the intake manifold gasket which would cause oil and water to mix.



    Are you sure it's water in the oil and not gasoline? If you had the timing so far off, the cylinders were probably filling with gasoline which eventually will end up in the oil pan. Are you seeing oil in the coolant as well? I could see possibly not getting all of the foreign fluid out of the oil just by changing the oil, but it would depend on how long the car sat before drained it and whether or not you changed the filter too.
    Can backfires really blow your head gasket?
    no a backfire will not blow your head gasket, it is designed to hold the combustion in the chamber. when a backfire happens it it is escaping into the intake or exhaust (less combustion). it sounds to me like something wasnt torqued correctly or is miss aligned or maybe a crack somewhere. if you already changed your oil then all the coolant should be out of your oil pan. how does the truck run? any smoke? noises, overheating?



    the best way to tell if it is fuel is to smell it. sounds like it needs to be taken back apart to me though
    Did you Magna flux heads to look for cracks?Did you seal head gaskets and are they correct?Check to make sure heads are true?Did you put new head bolts in and re-torque heads after running engine?Steel is crystiline and can stretch.You didn't mention year/make of your truck.

    HEAD GASKET HELP!!!!!?

    i just took of my heads and the pistons were filled with coolant. the problem is that the head gaskets looked good and the heads looked good, but someone told me that you cant tell if the heads or gaskets are leaking or blown just by looking at it. he said you have to check to see if the heads are leveled and he said to change the head gaskets even though if the head gaskets looks good, it can still be messed up. IS THIS TRUE??HEAD GASKET HELP!!!!!?NEVER reuse a head gasket, take the heads to a machine shop and have them machine them flat. then get a new head gasket and put it back together.
    HEAD GASKET HELP!!!!!?
    could be a cracked head too. it would be a good idea to have the heads serviced before you put them back on with new gaskets. as for the pistons filled with coolant you should have drained the radiator first, once you loosen the head bolts the fluid will run into the cylinders.
    HEAD GASKET HELP!!!!!?
    Inspect each cylinder and head closely. If you notice one cylinder or combustion chanber in the heads looks a lot cleaner than the others that's where the leak was. Water in the cylinder will literally steam clean the cylinder. Look at each spark plug individually. Also find a good straight edge and check your heads. It is a possible to warp a head and cause a gasket leak.
    that is true, anytime u take the heads off u should put new gaskets on, ur old gaskets may not go back in the identical position they were in and when u torque them back down they won't compress the way they should. this could cause a leak or even warp or crack ur heads. if u have fluid in the cylinders u'd better have the heads magniflexed to check for cracks and for level and hope it's not the block that's cracked.

    when u put the heads back on remember, they need to be torqued to specs and in the proper pattern. Ask a dealer or auto parts store for the specs.

    good luck
    Yes it is true.You can't tell by how the gaskets and heads look. If you have aluminum heads they will warp if the car overheated. They have to be leveled by a pro. And the gaskets always need to be replaced. Why take the chance by not putting in new gaskets.

    The head gasket on my Suzuki Vitara (1996) has gone: new gasket, new engine or new car?

    What shall I do?



    I don't have that much cash.



    I bought the car in Jan last year. Its a Suzuki Vitara 1996 model 4x4 2 litre Turbo Diesel LWB 5 door Auto.



    The head gasket has been a problem since November (with the radiator emptying of water quite quickly), but it drives ok, and has not let me down.



    The mechanic says I'm looking at 700 quid just to change the head gasket and see if anything else is wrong (if there is additional damage it could be up 拢2000 worth of repairs!)



    The mechanic suggested I would probably be better off getting a new engine put in. Is this a good idea; how much would it cost, and would additional parts have to be fitted alongside the engine? Which ones?



    What shall I do?



    CheersThe head gasket on my Suzuki Vitara (1996) has gone: new gasket, new engine or new car?replacing the head gaskets will cost you much cheaper that buying a new engine.

    but it is advised to let an expert mechanic to do the job and check for other problems before replacing the head gaskets
    The head gasket on my Suzuki Vitara (1996) has gone: new gasket, new engine or new car?
    Go for the new engine.



    Alot easier in the long run.
    The head gasket on my Suzuki Vitara (1996) has gone: new gasket, new engine or new car?
    700 is rediculas for replacing a head gasket. i would agree with having the head checked for cracks. throw on a gasket torque the head down, fill it with coolant and drive.
    Do the head gasket and make sure they send it off to be checked for cracks.

    Can I reuse my head gasket after only 30 mins of running time on the Car?

    I just changed my head gasket on my neon because of bent valves now i didn't line the head gasket up correctly and i had a massive oil and coolant mixer/leak. Car ran only once for about 10 mins total time before i noticed the problem. I was wondering if i can use the same head gasket and just line it up the right way the car didn't get hot and the gasket looks good just a little paint form the gasket onto the head is all i notice on it. ThanksCan I reuse my head gasket after only 30 mins of running time on the Car?yea dude u can reuse the gasket as long as its not ripped it will b fine
    Can I reuse my head gasket after only 30 mins of running time on the Car?
    You've heard the saying..there's not time to do it right but there's time to do it over?Your running a big risk of having to tear it apart again to fix it if the gasket doesn't work.I think it would be a big mistake to try using it over.But hey,you might get lucky.I sure wouldn't try it.
    Can I reuse my head gasket after only 30 mins of running time on the Car?
    sure, i would go for it, the gasket isnt torn and hopeful;ly will seat again,, check real good for tears,, did the blue on the gasket get removed,, you should be ok, just use the correct torque pattyern on the heasd wwhen u redo it,, three times to final torque..Art
    on an engine with a cast iron block and cast iron heads. i would go ahead and do it. but on a new contemporary engine thats all aluminum i would say dont do it. its cheap insurance to just use a new one. the problem with modern headgaskets is that theyre made of steel composite which is like plastic, nylon metal and other random things. while most old school engine headgaskets were either all steel, or copper or a mixture of both. steel and copper gaskets dont crush as much as steel composite, not to mention the composite gasket usually has this blue stuff on it from the manufacturer that rubs off when torqued down.





    save yourself the trouble. the average headgasket is less than 100 bucks.
    no.. the metal parts of the gasket are designed to crush a certain way, if you reuse it , it will likely blowout between two cylinders....
    I have done it before. Sometimes it will work fine. Especially if money is a problem and you have plenty of time. Just put it down right and tighten according to the torque pattern. If it doesn't hold, then you go back and start over with a new one.
    i have done it before. just be sure to follow the tightening sequence for the head and for the final torque add about 5-6 ft.lbs. to be sure to crush the gasket since it has been somewhat crushed already. has worked out fine for me both times i have done it. my wife has been driving her car for over a year now and i had to remove that head after running for 15-20 minutes because machine shop did not properly perform valve job.

    Head gasket question?

    I posted a question yesterday, for tips on how to change a head gasket...but since then, we had an emergency, and the car HAD to be used...i kept coolant topped off. and it has'nt been overheating, or no exhaust steam ect..but the reservoir still has been overflowing, even though it is'nt over filled, and oil is still trickling into the antifreeze and the reservoir.. which is a good indication that the head gasket IS shot...now i have'nt got it diagnosed by a professional, but i have had many people tell me it is a head gasket since it's common in the 98 taurus's..can you give me any more info, since it IS'NT overheating..yet..lol and will driving it 1 more time hurt it in the long run. even IF it's being kept cool and not overheatingHead gasket question?Have it fixed you,ll be better off in the long run.

    The oil will collect behind the thermostat and it will overheat, usually when you least expect it.

    The oil will also ruin all of you hoses.

    Head gasket question?
    what more info do you need,you have a leaky head gasket,if you keep driving it it will eventually over heat.When it does you stand a chance of the motor seizing up or doing other damage.I say strap a 55 gallon drum on the roof,fill it with water,run a hose down to the water bottle and keep on driving till the motor stops running....that is what you wanted to here ...right
    Head gasket question?
    yes driving it more will warp the heads even more its only so much they can shave off the heads before you can re use them then you are lookin at more money on a set of heads and if the reservoir is overflowing it is overheating but i would not fix that car its one of the worse ever made if you havent already fixed the transmission it will be the next to go thats the 2 main problems with the ford taurus the transmission and the heads i have 5 in my yard that i am fixin the transmissions in

    GB question -





    everything else about the car apart from the head gasket issue is fineThe head gasket on my Suzuki Vitara (1996) needs to be replaced: new gasket, new engine or new car?Well depending on the value of the car, I would just go for the head gasket. Most likely they will find something else wrong, but it should be minor. If there was any damage from overheating because of the head gasket I would think you would have noticed.



    I would not replace the engine, the car just doesn't seem worth that expense.

    Head Gasket blown what should I do (please read inside)?

    Now I have a car that is on the verge of having a head gasket blowm. (based on what the dealer saw when he was inspecting my car) I dont believe them, anyways my question is If I replace the head gasket, should I expect anything else to break down? and Should I even change the head gasket? The car has 120,000 miles on it. It is a toyota made in 1992. I dont want to sell it because It has a lot of sentimental value. I love my car more than any hot girl i can fall for. Please list what you think I should do and why. Thank youHead Gasket blown what should I do (please read inside)?If you love it spend the $1,000 to fix it but get a second opinion first on the repair.
    Head Gasket blown what should I do (please read inside)?
    Nice sentiment i haven't found my love car yet i like how u have. Now try to change the oil with high mileage oil that fills in gaps and cracks, this should give u more time to save or figure out what you want to do. Second option is to see, hear, and smell. see, white smoke coming from under the hood or over heating on the temperature gauge, hear, a rough or uneasy ride last smell your engine bay after about 30 to an hour of driving if u smell like a thick oily smell then its time for a new gasket. and when getting a new gasket try to get a longer lasting one that allows for more heat to escape but not enter a steel gasket with rubber lining will last forever but for better performance u can get a copper gasket with a carbon fiber lining its lighter and takes heat better. and if u don't fix this with in 3 to 4 months of any of the symptoms u may seis the engine making it unable to run to much heat will pretty much weld the pistons to the engine block.
    Head Gasket blown what should I do (please read inside)?
    first,stay away from that car dealer,he's trying to rip you off.next see a head doctor ain't no car worth that
    120,000....that head gasket should still be good. Barely halfway into the typical expected life of a head gasket.





    Before you start replacing major internal engine components(Which the head gasket is, complete ***** to access most of the time), run a few tests. Compression test will be revealing, if you get two cylinders low and adjacent, the gasket is leaking between them(Or the head's cracked). A vacuum test may also show some sort of error in the system, but those aren't as conclusive about head gaskets as compression tests are.



    Also, WHILE THE ENGINE IS COLD, you can remove the radiator cap and start it. If you see bubbles dribbling out of the radiator, or smell exhaust coming out, your gasket is starting to let go.



    You can also look on the dipstick and under the oil fill cap. If you see a milkshake, you have a leak between coolant and water passages. 99.9% of the time, this is a head gasket going out.





    Toyota loves aluminum heads, so if it was ever overheated, it's likely the head is warped and causing any issues that masquerade as a head gasket. You'd have to change it anyways, if you have this serviced, as you NEVER re-use a head gasket.



    Another symptom is loss of power/torque/fuel economy, hard starting, maybe the engine is cranking easier than it should.





    If you get white smoke when the engine is at operating temps, or if those operating temps are higher than normal, COMBINED with a significant coolant habit, you also have a telltale sign of a leak in the gasket. Or a cracked head. Struggling to pass emissions with a high HC reading is also not good, but it's by no means conclusive(A stuck open fuel injector or blown O2 sensor can also cause this in your case).



    Remember: the head gasket is a royal pain in the *** to get to, and you shouldn't change it unless you're ABSOLUTELY sure it's blown.



    If you elect to change it, now's a great time to do a head job on it. It may not need it, but you'll have the cylinder head off anyways, so you might as well. Besides, the components will be removed prior to the head being inspected for cracks and being milled flat(Which you absolutely must check, a warped head is a frequent cause of a bad head gasket). While yer at it, this is a great time to replace all the gaskets you can get to. Just make sure you know it's actually a head gasket going.





    I own a 1985 Ford F150, 4.9L inline six. 260,000 miles. I had a head gasket go over a period of two or three months. Every smptom and test I've described here I performed on my F150. I speak from personal experience here. Also, I changed it in my back yard for roughly 400 bucks, and that's counting the head work. It's possible to DIY if you know what you're doing, but it may take a while. A shop will charge as much for labor as they will for parts, and that's assuming your head isn't cracked. Mine wasn't even significantly warped, Carquest milled it and replaced the valve train. Old engine runs like a top now!





    I have the same sentimental attachment to my 500 dollar truck, by the way. :P It was given to me by my dad to fulfill a promise to his dad, now dead. It's never seeing the crusher.
    get some more opinions/estimates from other repair shops, the head gasket is either blown or not

    The head gasket on my Suzuki Vitara (1996) has conked out: new gasket, new engine or new car?

    I don't have that much cash.



    I bought the car in Jan last year. Its a Suzuki Vitara 1996 model 4x4 2 litre Turbo Diesel LWB 5 door Auto.



    The head gasket has been a problem since November (with the radiator emptying of water quite quickly), but it drives ok, and has not let me down.



    The mechanic says I'm looking at 700 quid just to change the head gasket and see if anything else is wrong (if there is additional damage it could be up 拢2000 worth of repairs!)



    The mechanic suggested I would probably be better off getting a new engine put in. Is this a good idea; how much would it cost, and would additional parts have to be fitted alongside the engine? Which ones?



    What shall I do?

    Oil changes don't keep head gaskets from blowing. Toyota should cover whatever the warranty says it should. Most head gaskets blow because people let the coolant get low.

    i have got a mk4 astra 1.6 8v 98. Has any body got a blue how to change the head gasket. I have never done 1 b4, is it easy job?Head gasket, mk4 astra?Easy and hard are subjective terms. Some would find it easy and some would find it hard and others everywhere in between.

    If you have to ask then there is a good chance you will find it very hard.

    The head will need to be skimmed to get a new good seal and the cambelt has to come off too. lots of difficult stuff for a novice mechanic.

    Blown head Gasket what to do!!!!!!?

    Ok, I took my car to pep boys and they told me that I have a blown head gasket. they are charging me close to 1300 to get it fixed. These are my questions,



    1.)what do they mean by rebuild the engine and is it necessary for a blown head gasket?



    2.)They also told me that it would be better to get a new engine is this also necessary and what is the reasoning behind it?



    3.) can i change the head gasket at home? is it difficult to change?



    4.) is there somewhere that i can take the engine to get surfaced?



    5.)do other places charge less to fix a blown head gasket?



    Thanks to anyone that answers my questions.

    O AND BY THE WAY I OWN A 1996 NISSAN MAXIMA WITH A V6 ENGINE.

    Again any help is greatly appreciated!!!!!!!!!!!!Blown head Gasket what to do!!!!!!?I cant say that I have ever worked on a nissan maxima before, but I have changed a few head gaskets in my day. And I did it at home. You will have to take the exhaust manifold off and most likely have to take the intake manifold off as well. For the details on your specific vehicle I suggest you go to the library and look for a repair manual for your vehicle. If they wont let you borrow it, copy the pages you need. Make sure to follow the torquing sequences. Most libraries have a full line of Chilton's manuals. As for resurfacing it you shouldn't have to unless you over heated it or something, but in most cases it should be fine. Could answer the rest of the question better if you had said if it had over heated or given more info.



    You should ask them why they said that it should be rebuilt, or need resurfaced. They might just be trying to get more cash out of you. The resurfacing is called milling and it should not need it. that can be done at any auto machine shop if need be. If you have one head Milled you should do the same to the other.
    Blown head Gasket what to do!!!!!!?
    you might as well invest in a new car dude..seriously..if you've blown a head gasket..your engine is toast. it is impossible to change at home.
    Blown head Gasket what to do!!!!!!?
    well i would say that the quote they gave you is about right, you can call around and see about some prices from other shops, as for replacing the motor, did you drive it alot and did it overheat? if so you could have warped the heads and then a new motor would be cheaper considering you can get the vq30 which is the motor i think is in your car for around 1500. also as far as you replacing it, well are you a mechanic or are you mechanicly inclined? if not i wouldn't suggest it because there is alot of work that goes into it. I hope i was able to help you and if you have any other questions let me know
    I believe that's 10.5 hours book time. So yeah that's about right. I always take the heads to the machine shop on every one of my customers cars. Once you have heated it up the heads get warped, and the price a machine shop charges to surface them and clean them up so I can inspect them is minimal compared to the price of dis assembly again after the job is done and the heads end up being warped. If you have the time and patience you can do the job yourself. Get a manual and step by step go through it. Might take you a few days if its your first time but you will end up spending about $300-$400 on parts and machine shop costs. Still alot better than the $1300 they quoted you at.

    Head gasket?

    can any 1 tell me how easy it is to change the head gasket on a nissan micra gsx 1300 1989Head gasket?if you dont have access to the correct tools then very difficult as head bolts need to be torqued correctly. and u need to also set the timing belt correctly or bye bye engine. but with all tools and a good manual its reasonably straigt forward
    Head gasket?
    first of all, you need to be a qualified mechanic with the right tools, and secondly you may not need to replace it if your cars only over heated they can sometimes just skim the top off.
    Head gasket?
    Hi there,

    I agree with Corey, If you have to ask then maybe you shouldn't attempt the job. If your head gasket is leaking what has caused it to leak and you may need specialist machining services to skim the cylinder head if warped and this can only be checked using special tooling too.
    Try reading the Haynes manual for your car would be the first stage to see if you can tackle the job. Make sure you have a good tool kit to cover the job and allow plenty of time for any inspected problems. as said above by the others If its only a one off it would be easier to go to the garage Good luck
    normally, if you have to ask that question.... you prob shouldnt attempt it!
    as easy as changing your scocks
    Hi



    If you're mechanically inclined then its basic straight forward Janet and John stuff. However, if you're not mechanically minded, or you just try your hand at the odd oil change now and again, then you should probably leave it to a man who can.



    Very best regards

    If you need to ask what tools you will need, you probably don't have the skill to do the job.

    What tools will i need to change a cylinder head gasket on a citreon ZX Preg?
    first you will need a torque wrench a work shop manual ply a lot of paitence when off have the head skimmed
    What tools will i need to change a cylinder head gasket on a citreon ZX Preg?
    a rubber mallet.

    socket set.

    torx socket set.

    scraper.

    spark plug socket.

    torque wrench or tightening gauge with breaker bar.

    screwdriver set?

    workshop manual, as cylinder head bolts require certain tightening pressures and sequences to fit the head to the block with out causing the head to be distorted or un even.

    This list really does NOT scratch the surface.

    your going to need the head skimmed by a speiailist, you need silly things like feeler gauges. The only thing you can do is buy the tools as you need them.

    Good luck though.
    check the car workshop manuals
    No offence intended, but you probably don't have the expertise. It's not a job for a beginner, several critical issues like the cam belt are involved. If you make an error, you'll end up spending more than having the job done by a Citroen specialist. Look at the relevant Haynes Manual to see whats involved.
    A fu**ing big hammer!!!
    scrap it or be prepared to strip half the engine down to get the head off, by the way its got wet liners so be very careful when taking of the head

    If a car has a blown head gasket, would water in the system cause the same effects?

    If a car has a blown head gasket and the antifreeze, is mixing with the oil ... you get white smoke, discolored antifreeze in the reservoir, and a milky white goope in the motor oil ... RIGHT??



    My question is ... if an owner springs a leak in the cooling system and has been filling the cooling system with straight water, and had an oil change in the process ... will that water cause the same effect as the antifreeze? White smoke? milky residue? discolored coolent?If a car has a blown head gasket, would water in the system cause the same effects?Probably. But the most obvious effect of a blown head gasket will be overtemperature and a loss of coolant, as hot combustion gases leak into the cooling system. Also, coolant will seep into the cylinder during the intake stroke, causing vast amounts of white smoke.
    If a car has a blown head gasket, would water in the system cause the same effects?
    Yes =^ )
    If a car has a blown head gasket, would water in the system cause the same effects?
    yeah, it will. It will also overheat faster
    yes it will as any water mixed with oil will turn the oil milky.

    Replacing Head gasket????

    I have a 1JZ toyota engine and want to replace the head gasket. Do I need to do anything to the head or just remove it and replace the gasket. Note: I am also planning to change head %26amp; main bolts. Thank you 4ur input. :-)Replacing Head gasket????It is not like replacing a valve cover gasket. The bolts must be tightened to specs. You need a ratchet that shows ft.lbs of pressure. You need a torque wrench. Read up on it. You also want to make sure the head is not warped.
    Replacing Head gasket????
    First off look at the old gasket and headface (after removal) for obvious signs of corrosion or burning.You should have the face of the head checked for straightness or check yourself if confident. You can do this by placing a known straight edge such as a steel rule across the gasket surface at all angles (corner to corner, down the center, along each edge) and then trying to put succesively smaller feeler gauges under it to find any out of flat warp. You can usually get away with about 10 thou of warp on a 4 cylinder head on a lightly stressed engine. Any thing on or near that I would suggest a surface grind. (head skim). If the engine has had overheating problems and oil or water contamination I would go for a pressure test too. And dont forget to change the oil and water after and BE SURE you have the timing correct on reassembly.if you are unsure turn the engine by hand several times before trying to start.If it locks up dont try to start it and recheck your camshaft timing. Sometimes its best to machine an alloy head just to clean the gasket surface. Good luck.

    Does anyone know how hard it is to change a head gasket on a 96 dodge avenger.?

    if you dont already know exactly how to do it, i suggest you don't try and leave it to a professional.Does anyone know how hard it is to change a head gasket on a 96 dodge avenger.?Depends on whether it is a 4 or 6 cylinder, and whether you are a better than average mechanic. Get a repair manual and read up on the R%26amp;R section of what it takes, and if it sounds like greek, you might be better off to pass on doing it yourself. How hard it is will depend on your skill levels in mechanical work and how well you can understand and do something you you have not done previously. Also, you need tools, like a torque wrench, for proper assembly.

  • How do u change a head gasket for a 97 geo tracker 1.6 litter?

    unbolt the exhaust manifold. You may be able to get away with not undoing the intake manifold..in many cases you can. this engine has a timing belt so align the timing marks prior to removing the timing belt. undo the throttle linkages and any other brackets. Drain the engine coolant. unbolt the valve cover then remove the spark plugs. Remove the cylinder head bolts then remove the head. clean all the surfaces thoroughly then replace in the opposite sequence. once you have it together change the oil and add fresh coolant then give it a whirl.

    How hard is it to change a head gasket on a rover 414?

    i bought a car ( rover 414 s reg) there seamed to be no problems with the car but on my second drive in the car the engine over heated . there was no water in the cooling system, so topping it up i carried on and few more miles the water was gone again and was smoke coming rom exshaust. i was told it could be the head gasket has gone so i burning water in the fuel. how hard is it to replace the head gasket? any help or advise would be greatly appreciated.. thanksHow hard is it to change a head gasket on a rover 414?Check the oil filler cap for creamy mayonaise type gunk. check the coolant bottle for the same.



    If it is clean, the head gasket HAS NOT failed. Its usually the inlet manifold gasket allowing coolant to enter the cylinders.



    If it is the head gasket, Its one of the easiest modern engines to change. Get a haynes manual for the basic description, but I'll give you some extra advice its best to follow.



    Do not use cheap no-name gaskets. Only use the oem payen type. The land rover MLS gasket is the best. Get one from a land rover dealer. tell them you want it for a Freelander 1.8. Same engine.



    Do not bother with the up rated oil rail available. Some people will tell you its needed. It isnt exept on the freelander.



    Measure the liner stand-proud above the block face, using a straight edge and feeler gauges. It should be more than 2 thou. 1 thou is acceptable, less than that and the liners have sunk and the new head gasket will fail again quickly. New engine time.



    The head bolts can be re-used as long as they are in good condition, screw each bolt into its location with the head still off. They should screw easily to well below the hight of the head without effort. if they bind at all, get new ones.



    Look at the head face, if there is a groove where the fire ring sits, it has gone soft from over heating. you can get it skimmed flat if its not too deep, and use a head saver shim. better off with a new head.



    DO NOT skim the head if it is flat. they are surface hardened and skimming can remove that layer.



    Make sure both faces are very clean before re-assembly.

    its not that hard, but having over heated it you could have warped the head, just makesure you get the timing correct there is a tool to lock it in place and most of all replace the head bolts, i didnt and when reassembling it i snapped one and had to drop the sump which was a work up, because they are stretch bolts you can only use them once, apart from that i found it rarther easy, before i did it everyone umed and ared about it but dont let them put you off, av a go its goo learning, by the way mine was a rover engine not the honda engine, good luck

    Head gasket?

    do you have to changed the headbolt to changed the head gasket?Head gasket?why change it, just use some sodium silicate block sealer :)
    Head gasket?
    It depends on certain engines. So, yes. Best to get a repair manual for that vehicle, and it should tell you that warning there.
    Head gasket?
    no
    Some require it, and some do not. A lot of the head bolts are called %26quot;torque to yield%26quot; bolts, which are made to stretch and create sort of a tugging action on the head to the block. These bolts will not spring back into place, and are ruined once removed. Putting these bolts back in will cause more problems than you want to think about...

    Even if the bolts are reuseable bolts, there is a lot of heat which has a potential of expanding the metal...

    in my opinion, I would change the bolts to save you time, money, and headaches!
    No, but you might have to have the head ground if it has been overheated.
    mark d nailed it. check your manual. some cars reuse, some replace. typically older cars reuse, and smaller imports replace but that is just a rule of thumb. if you have a reuse car, make sure you wirebrush the threads of the bolts, and tap the holes in the block so that you dont get a false torque reading from all the rust and gunk on the bolts. and dont forget sealant on any head bolt that penetrates a water jacket in the block.
    As previously mentioned, some do and some don't. The mentioned %26quot;torque to yield%26quot; type do for the reason that Mark D mentioned about the stretching. Later Ford 4 cylinder engines require replacing cylinder head bolts, like the Escort engines and such. Most of the 6 cylinders and V8s do not. Here is an easy way to tell if it is a torque to yield type: look at the head of the bolt. If it is the regular 6 sided type, then most likely it does not need to be replaced. If it has 12 points or looks like it takes an allen wrench to take it out, it will be a torque to yeild type.
    If the torque specs. are torque-to-yield, YES.

    1998 jeep cherokee 4.0 head gasket?

    Hey I want to change my head gasket and get the head resurfaced and everything but everyone keeps telling me that its too much of a job to do myself. It doesn't seem like it would really be that bad though. Does anyone know where I can get step by step instructions for this just in case I forget where something goes though? Or if somebody can give me some directions it would be appreciated. Thanks.1998 jeep cherokee 4.0 head gasket?well for step by step the closest thing you can get to that is a chiltons/haynes manual, but its just like any other you have to remove the manifolds and fuel system. it can be quite a job depending on the room and everything over the head in question, most jeeps are at least 6 bangers so you might consider replacing both if your doing it for any other reason than one side needing it. just start removing things and mark every set of bolts to insure they go back where they need too. you will ahve to depressurize the fuel system and there should be a valve along the fuel rail to do this. of course unhook the battery. when removing things like the manifold you want to alternate the bolts when you remove them as you would lugnuts. so you dont warp it when removing or replacing. try to mark all the wires too, best way is to use masking tape and put an indicator like 'a' on the wire and 'a' on the other end of the connector that it attaches to. you do not have to disassemble everything so try to keep it together if possible. in other words you dont have to open the throttle body up just remove the whole thing from the base. then remove the manifold and most likely some sub systems like the alternator spark wires ,etc to get to the head in question. also if you have multiport injectors remove all the bolts fastening it to manifold and once loose the injectors will pop out will a little pull as they are just pushed in and sealed with o rings



    then remove the exhaust manifold bolts but dont remove the whole thing unless you have too. now when you get to the head its even more important here that you remove the bolts in an alternating fashion. say you have 10 head bolts and we number them from left to right from top to bottom. then break loose first number 3 then 9 then 4 then 7 then 2 etc and of course break loose all before you loosen anymore. and cut a piece of cardboard out and label it and put holes in it to match the headbolt layout, as you remove a bolt put it in the right spot in the cardboard, this way you know where the longer bolts go in case they are not the same size. and do this even if your getting new bolts

    just use your common sense and mark everything since you lack experience this will truly benefit you as it could be a week before you put it back together. now if the head needs to be trued and pressure tested you should cover the cylinders with non fibrous cloth and coat them with a light covering of oil to help prevent rust build up. and while you wait start preparing all surfaces for the new seals. use a putty knife and keep the knife just above parallel with the surface as you dont want any knicks or scratches in the matting surface or you have leaks. and try not to get any old gasket in any ports on the block



    now when you go to replace it of course you will need all new gaskets and you really should get new head bolts too, and at the very least use a torque wrench for the head bolts and really again since you lack experience you should use the torque wrench for the manifolds too. you can get the torque requirements from the chiltons/haynes manual which you should invest 10-20$ in for this job.

    also coat the head bolts with oil before you put them in which helps in antiseizing.

    now for any rubber gaskets and orings make sure you coat them with oil, and for paper gaskets a thin layer of permatex is good unless the manual tells you otherwise. and when you get to the injectors if multiport you have to make sure they pop in correctly as it wont ake too much force but you have to make sure they seat correctly. now when its all back together make sure you turn the ignition on several times before you try to start, this allows for the fuel pump to repressurized the system. and you really should have someone else do this while you inspect under the hood for any fuel leaks before you actually start it. now this is a sloppy layout for the answer but it should get you going
    1998 jeep cherokee 4.0 head gasket?
    If you're handy with taking stuff apart on your jeep, it will be very easy until you remove the head. From there of course just let a shop rework the head, then bring it home and toss on the highest quality gasket you can find and torque to factory spec. As others have said, a manual will help you greatly. Remember now is the time to consider any other maintenance/cleaning and upgrades you may want to do while the parts are out. Don't get discouraged by people telling you it's a huge job. The 4.0 is one of the easiest engines to work on and everything is very accessible. Just take your time and be careful to do things right.



    P.s. Port and polish? :D
    1998 jeep cherokee 4.0 head gasket?
    If you are handy (mechanically) with vehicles I'd say go for it. If you are not real handy I'd say don't attempt it. This will require a good selection of handtools and a service manual from Mitchel or Chiltons. This will also require a torque wrench, gasket scraper and other specialized tools. You can take digital photos as you do the disassembly and put parts in marked plastic baggies. This will assist you in reassembly and keep parts from being lost. This is a pretty big job and I would guess that since you asked the question here you probably shouldn't do it (no offense intended).



    Hope this helps in your decision.



    Bob
    It's not too big of a job. Get a Chilton manual for reference, and allow enough time to get it done.

    Heres a tip; take a few %26quot;before%26quot; pictures, and take a few more during the disassembly process.

    Does it make sence to change my head gasket once again?

    I have a 1995 Honda civic, I had an overheating problem in 2003, and I had a reconditioned replacement of my head gasket and a radiator replacement shortly after; the car was fine until about 4 years after the replacement, I started to have overheating problems once again, in fact I was told up until recently that the car overheats because of ruptured radiator hose, each time this happened I have had my radiator hose replaced, however there were a couple of times when the car overheated and the reason was unexplained, but, now I have been told by two mechanics that I have a blown head gasket once again. This car has overheated since the summer of 2007 about 10 times maybe more. I am becoming somewhat paranoid that even after having a replacement head gasket the problem may still exist, as I have heard horror stories of this. Can someone please tell me if it is worth fixing once again? has any one had similar problems with this type of car? Your opinions and suggestions would be greatly appreciated.Does it make sence to change my head gasket once again?A blown head gasket should result in continuous overheating and not periodical. It might be that your cooling system needs flushing completely if your car is over four years old. Also on the suction side of the radiator, the hose has a spiral wire inside to prevent collapsing. It may appear OK from visual appearance but under heat/pressure, it will close off flow of cooling fluid and cause overheating. Reach down and feel both hoses and try to compress them by squeezing. If you can squeeze them together by hand, then the spiral wire inside the hose is surely deteriorated and allowing you to do so. Replace it and recheck your heating problem. A 'blown' head gasket is usually audible making hissing or whistling noise. This is caused by a warped or scored head or engine block. The aluminum blocks of this model tends to sometimes do that. Also, check your oil to see if it has water in it (yellowish emulsified coloring). Cracked/blown gaskets,blocks,heads should exhibit this.
    Does it make sence to change my head gasket once again?
    that's not uncommon on one that's had previous problems before,its possible it does need another head gasket but id get a few more opinions on it before i had someone tear it down,they can run a compression check on the engine and check for a bad head gasket,if it got hot enough though it will blow a head gasket,so this could be the same cause of it happening again,it only takes one good time of getting it hot to blow another head gasket,good luck on it,

  • Head Gasket on 1988 Ford F-250 with a 302?

    Is it very hard to change a head gasket in a 1988 For F-250 with a 302 its also a 4x4Head Gasket on 1988 Ford F-250 with a 302?buy a CHILTONS repair manual, not haines and have at it dude.. go to the engine section and look for cylinder head removal and re installation. follow the instructions to a %26quot;T%26quot; including the parts it says to replace and you will be fine, as well as gain confidence to do mechanical jobs to your own vehicles to save tons of money in the future..
    Head Gasket on 1988 Ford F-250 with a 302?
    It's very hard to change a head gasket in any car. Unless you have quite a few years of automotive experience, you probably shouldn't try to do it yourself. I've been working on my own cars for over a decade and barely feel confident about that repair.
    Head Gasket on 1988 Ford F-250 with a 302?
    If you handy with tools it is not all that hard. Drain the coolant, remove the exhaust manifold, remove the intake manifold, take off the rocker cover(aka valve cover), remove the rocker arms, and the push rods. Remove the head bolts, lift the head off, take the old gasket off, clean the surface on the block and the head, put the new gasket on, and reverse these steps. Make sure you toqure everything corectlyas you reasemble.
    there are some engines i wouldnt do the head gasket myself again like our 3.8 windstar that was crazy and i never did get it right but a 302 is very simple in comparison and if your mechanically inclined at all you should be able to do that repair like i said fairly simple on that engine
    Never seen a 302 in a F-250.

    Might have a 351-W, if so, hard to do

    How important is it to have your cylinder head resurfaced when replacing your head gasket?

    I have a 1996 j-body sedan with a 2.2 engine. I have an external leak in my head gasket (leaking coolant), that apparently is not affecting compression and there is no coolant/oil mix. I narrowed down my choices to 2 main options for fixing it:



    1. Have it fixed locally for about $1000 including gasket kit, resurfacing, labour and tax.



    2. Have it fixed by a friend who is a Toyota tech for about $500 (parts/labour/tax). But I would need to drive the car for about 300 hwy kms, and would likely not be able to have the cylinder head resurfaced.



    Any thoughts? Would also appreciate suggestions of other associated repairs/maintenance that I should consider (timing chain and tensioner were done 40,000km ago, coolant changed 10,000 km ago).



    Thanks!How important is it to have your cylinder head resurfaced when replacing your head gasket?If the enging did not overheat, then it would not likely have warped the head, so you should be able get away with passing sandpaper on the mating surface of the head.

    Save the $$
    How important is it to have your cylinder head resurfaced when replacing your head gasket?
    that sounds too expensive either way.

    There is a reason for the gasket to leak so I would certainly get the the head resurfaced.
    How important is it to have your cylinder head resurfaced when replacing your head gasket?
    Have the head checked for cracks and warpage. The 2.2 will crack near the front head bolt on the drivers side. Get new bolts too, the old ones may break.
    Both people want to take you to the cleaners. you don't need to surface the cylinder just to replace the head gasket, as long as there isn't a crack you won't have a problem. If you have any tools do it yourselfe. Check your coolant to see if it's still at the required temp. for your area. I would get a third quote on the job if you can't do it yourselfe!
    No way to tell till the heads come off. They'll just lay a straight edge on it and see if it's warped too much. The #2 friend hopefully won't put it back on if it's warped. If it is, he'll be able to get it planed for a whole lot less than $500.
    Resurfacing the head will insure that you have a good matching surface to the block. This is to guarantee that the problem does not repeat it self. Sometimes the pressure will cause a slight grove in the head. This grove may not be noticeable. In the long run it is better to resurface the head.
    Cylinder heads have a set tolerance for warpage. If it us under, your OK. If not, the gasket will leak again. I would have it resurfaced.
    If it's leaking towards the front right corner of engine (while looking at eng from front of car) then just get it replaced. That is a very common leak area on the 2.2 chev
    Getting the cylinder head resurfaced is probably the best way to go. It will ensure that the gasket is seated correctly and compressed evenly. An even compression on the seal will help assure that it won't leak.



    Another factor to take into consideration is that it might be a rough patch in the cylinder head surface that is causing the leak. In that case, you would HAVE to have it resurfaced, or else it will never seal.



    One final thing to consider, is that if you take it to a shop, their work is usually guarunteed and warranteed. If something goes wrong and is the fault of the shop, they have to pay for it. If something goes wrong with your friend, you are SOL.



    I would suggest taking it to a shop.
    take it to a mechanic localy that 2.2 engine has an aluminum cylinder head its very important to check the deck of the head and resurface if it needs it BUT U MUST CHECK IT. ALUMINUM IS PRONE TO WARP DESPITE BEING OVERHEATED OR NOT most mechanics especially backyard self taught no schooling mechanics dont know how to take an aluminum head off to help prevent warping spend the 1k ull get a warranty too. 1k is cheap compared to what i charge but i also check valves and spring pressure to because ur already there.
    you should always have it resurfaced

    I have change my head gasket!! put new water pump in and had 3 new thermostat s car will not bleed up?

    so i took out my thermostat and every thing ok ? try bleeding it now for 2 weeks and no luck ? so was just thinking will it b ok to run with out thermostat for a while ? cos i sick ov it just looking at me on the drive, lolI have change my head gasket!! put new water pump in and had 3 new thermostat s car will not bleed up?As with your other question, it would help to know what car you are on about.
    I have change my head gasket!! put new water pump in and had 3 new thermostat s car will not bleed up?
    Need more info about the car make model year to help. Did you flush the cooling system?
    I have change my head gasket!! put new water pump in and had 3 new thermostat s car will not bleed up?
    1 r u putting thermostate in upside down ? maybe?

    2 hoses,,,if old and soft they can go flat under pressure and heat

    3 car without thermo will run cold,,,bad for engine but ok for now untill you figger wtf is going on
    Whatever could you mean by %26quot;car will not bleed up%26quot;.

    And NO, the car will not run correctly if you leave out the thermostat.

    Also, what does this mean, %26quot;try bleeding it now for 2 weeks and no luck %26quot;

    What are you bleeding.
    so your saying you can,t get the air out? try doing it this way. start your car and once the thermostat is open take 1 of the heater hoses off for a second and put it back on. if you have air that should let it out.
    Yes it will run.

    Thermostat controls the coolant in your engine's cooling system. my car lives without a thermostat for almost 7 years.



    I removed it since it always got rusted and stucked up causing my temperature gauge to lights up.



    Since i removed my engine's thermostat, so far in 7 years time, i haven't experienced my car overheats.



    I lived in the middle of the equator, it's hot in here.

    As long as my main fan and auxiliary fan is working, i have no doubt of having an engine without a thermostat.
    First things first, you are using the right technique aren't you? Letting the temperature come up so the thermostat opens, and turning the heater up full-bore? If you don't you'll never bleed it properly. The entire system must be flowing freely for a successful bleed.



    You don't say what car, but some have supplementary bleed valves, usually on the heater piping, which must be opened as well.
    look on intake should be bleeder valve on or near thermostat housing , it is used to bleed air from motor top.
    I know this may sound strange but some vehicles need to be raised in the front to bleed air out of coolant system. I would call your local radiator repair center and ask them for the proper bleed procedure. DO NOT remove any hoses after allowing the engine to warm up. You could be very badly burned!!!! Good luck.

    Do you have to take the motor out of a chevy lumina to change the head gasket?

    absolutely not.with the intake off, all of the required bolts can be taken out. its a time consuming, but relatively easy job to do.Do you have to take the motor out of a chevy lumina to change the head gasket?Yes. If you want to do it right.
    Do you have to take the motor out of a chevy lumina to change the head gasket?
    no you do not have to but would make it easy if it was. btw is the motor a 4 cylinder or a v6, if its a 4 then you could do it with the engine in the car

  • HOW TO CHANGE A HEAD GASKET?

    I have a 1994 mercury cougar, and its blowing white smoke out of the tail pipe that smells like gas. i need step by step instructions on how to do this job.HOW TO CHANGE A HEAD GASKET?That job is complex and should be done by someone with experience- especially with an overhead cam engine. It's OK to know how to do it. Take Walt's advice and read a good repair manual.



    After the head is off, it still needs to be checked for warpage and cracks and reconditioning it cannot be done with any common tools around the house. If you have the skill and plan to do this job, make sure you have a way to get the head to a machinist. I've already said too much, if you never have worked on an engine.
    HOW TO CHANGE A HEAD GASKET?
    Spend the $20 and buy a repair manual. I don`t have time to write a book for you with step by step directions for some one that may or may not know what they are doing. And if you have to ask how. Chances are you have no skills whatsoever, and probably no tools either
    HOW TO CHANGE A HEAD GASKET?
    You should know this is not an easy job to do, not just because you have to take the whole top of the engine off, but when you put it back together you need to torque every thing back down in a specific sequence. The best thing to do is to take it to a shop, I know it is going to cost a lot, but at least you know it will be done right.

    If you can't afford to take it in then go and get a repair manuel for your car type and year. I like using a Chilton Auto Repair manual, they are done by people who take each issue and do it from start to finish showing step by step what you have to do. A manual is about 20-25 dollars, you are also going to need among other tools a torque wrench, possibly tubing wrenches, (they are like open end box wrenches, but the opening is smaller so it will fit over the tubes for the carburetor or throttle body because these will need to be taken off with out being broken off, because these are easily broken).

    These are just some info that I can give it there is a lot more, so go and get a manual and or talk to mechanic about what is involved in this kind of job.

    Good luck to you....peace....
    the 232 v6 ford used thoughout the 90's had an iron block and aluminum head. after countless heat cycles (running the car, getting it hot then letting it cool) the different expansion and contraction rates of the metals will cause the head to crack. white smoke is steam which means you are leaking coolant into the combustion chamber. your head is cracked. you can try some sealant but you are likely looking at a costly repair. i hate to say it but its probably time for a new car, or at the very least a new engine.



    for future reference:

    white smoke=coolant

    black smoke=unburned fuel and you are running rich

    blue smoke=burning oil



    they are all bad
    This is not exact.. and no way conclusive as i;m tired lol...but from what i can remember:



    DISCONNECT BATTERY



    Remove all HT leads + Spark plugs



    Take off rocker cover



    Remove water pump



    Remove Air filter and housing



    Remove Inlet manifold



    Remove exhaust manifold



    Mark pulley timings up on the cam belt so you can make sure when the belt is put back on it is all in time..if the timing is out there is a high risk of killing your engine.



    Release tensionsers and then remove auxillary belt (fan belt) and your cam belt.



    Remove cylinder head



    Wellah! your head gasket is reveled..make sure you put the new one in correctly. And then re-assemble...it is strongly advised that you replace all your gaskets once this has been done (i.e Water pump gasket, rocker cover gasket, exhaust flange)



    Also..you sure its the head gasket? check for oil in water and water in oil..is it over heating?.. this is a big job to do so make sure it is what it is. People do make a big fuss over this job...its not hard as long as you are confident and remember ho to put it back together

    Head gasket change on a 2ltr sri vectra.?

    can someone seriously give me some help on doing this ihave the haynes manual is there anything they dont tell you...Head gasket change on a 2ltr sri vectra.?Keep everything clean. Drain the coolant before. Change the oil and filter afterwards.



    You need quality sockets and a breaker bar to loosen the head bolts. I used Craftsman impact sockets after cracking (and Sears replacing) several regular Craftsman sockets.



    The cam - crank alignment is CRITICAL. Make sure that you align it exactly as it was before.



    As you are taking the head off, it is a good time to replace the timing belt/chain, and have a valve job done.

    I have got a volvo t4 1.9 the head gasket went i had that changed and the rad waterpump and heater matrix?

    there was oil getting in the water. Now there is a lot more oil getting in the water. When the engine is cold i take off the rad cap and oil comes out the cap as if there is pressure pushing the oil into the water. There is no water in the oil. Someone said it might be the oil cooler or the turbo?? Has anyone had a simlar problem?I have got a volvo t4 1.9 the head gasket went i had that changed and the rad waterpump and heater matrix?Might be a cracked head. Have your mechanic do a pressure bleed-down test. It is a crack in the combustion chamber dome. Probably between the valves. That will let the charge mixture into the cooling jacket of the head with out getting water into the oil.

    Broken Head Gasket Seat Leon tdi 1.9 diesel 2000?

    Hi all



    One week ago I bought a seat leon for 拢2.4K from a private seller and two days into driving it the coolant light started flashing. The car has a full service history having had its cam belt, water pumpa dn head gasket changed at a garage by the previous owner only last June. Nonetheless I got very worried, stopped driving it and called a mechanic friend of mine who is very very good... Unfortunately he told me the problem is with the head gasket again and that either the garage didn't do a good job or in a worse case scenario, the cylinder head might be changed. The repair will cost at least 拢500

    It's clear I've been had by the seller but I don't want to get dragged into a long battle to see my money back and I've thought about taking it back to the garage and complain but I see no point as the car might break down on the way and if indeed they did a poor repair in the first place, they might do it again.

    I am prepared to get it repaired by someone who knows what they are doing (my mechanic friend is really v good) but I'd like to know whether I should leave it alone as it seems like the head gasket has gone twice in its lifetime now... Any opinions??



    thanks!!!Broken Head Gasket Seat Leon tdi 1.9 diesel 2000?try to have it repaired on Racepages..check here http://www.racepages.com
    Broken Head Gasket Seat Leon tdi 1.9 diesel 2000?
    I don't get all this lingo gibberish?!? What's wrong and what is the question? Is it a seat (your ***) or a Gasket (an artery) or your head that is broken? Also, is deisel in reference to heroin? Cos you should cut that out now, unless it is another slang for morphine: legally described by a physician. Either that or your car.

    Is it hard to change head gaskets?

    hey gents, im about to buy a used toyota w/ a blown head gasket. i do not have any formal mechanic training, worth it?Is it hard to change head gaskets?Not hard if you have the right tools and knowledge.... and if you are asking, don't try to do the job yourself or buy another car.
    Is it hard to change head gaskets?
    Do not buy it. The top half of the motor must be disassembled to replace that gasket and the head must be machined to check for warpage. In a lot of a cases a blown head gasket means replace the motor. Do not buy it
    Is it hard to change head gaskets?
    yes it is ,because you have to have the head checked for cracks and warping once its removed,and if its a bad head you,ll hae to replace it,and that can run in to some money on a toyota,if you have the knowledge and patience and a good repair manual and real good selection of tools you might can do it other wise if you have to pay to get it done its going to be expensive,about 800-1000 bucks worth of repairs on that one,good luck with it.
    Replacing a head gasket is no place for a rookie mechanic to start learning!



    That would be like a high school baseball player trying to be starting quarterback in the Superbowl.
    stay clean away from it if you don,t know what to do because it can be a task if you don,t know anything.
    a head gasket is easy to do if u have the correct tools and training , if u don't i would not attempt it your self have an expert look at the car and give u advice before u buy it.
    Im doing a head gasket right now. Its not as hard as you might think but it is extremely involved. I just spent a whole day scraping and cleaning. If you don't know if you like this kind of stuff then you may want to look somewhere else. You are going to need plenty of time and a Haynes manual. In fact spend a few bucks on the manual and do some reading before you buy the yota.

  • Does Leaking Head gasket affects the running speed of my car?

    i got a 1995 BMW 316i and kind of running slow especially if it is a little hilly. If i change the pipe and gasket itself, would that make any big difference to a car?Does Leaking Head gasket affects the running speed of my car?it pays to know why the leak has occurred. do you mean manifold gasket? Head gaskets usually show up blown some 10 days after serious overheating of the motor. if a head gasket, you will lose power, overheat your motor, perhaps lose coolant, contaminate your oil, perhaps warp your head....... If manifold gasket, you will have excess noise, motor overheating, reduced power, perhaps warp your head and/or manifold.....Both faults will reduce top speed, but you shouldn't be using that anyway, but the heat is the biggest problem, and the damage it does. Either way, FIX IMMEDIATELY, %26amp; do NOT drive it far or quickly til it is fixed.
    Does Leaking Head gasket affects the running speed of my car?
    %26quot;The pipe?%26quot; I'm curious as to what you think a head gasket actually is.





    Yes, it is possible for it to make your car slower. The head gasket is what contains the pressure inside the combustion chamber. It seals the gap between the cylinder head and the engine block. If that seal is broken, some of the combustion gases can escape, meaning less power gets to the wheels. The difference could be small for a while, or it could be big immediately...but it will be big eventually.

    you gotta be more specific what engine?
    After i changed the head gasket on my 98 chevy silverado?
    GM always has the firing order cast on the intake manifold of thier domestic engines. It always starts with 1.
    The firing order would be for the V8

    firing order for V6 1-6-5-4-3-2

    Do you think its my head gasket that needs to be change?

    i have to put water in my radiator every day, its always low. the coolant recovery tank always empty and when i take the dip stick to check the oil level it all white at the end. is it the head gasket

    or some other gasket?Do you think its my head gasket that needs to be change?It is definitely a head gasket or the head itself. With the oil being all milky, you should not drive the vehicle until it is fixed, as the oil loses all its lubricating ability when coolant is mixed with it. Also,

    it could overheat.
    Do you think its my head gasket that needs to be change?
    yes take it apart
    Do you think its my head gasket that needs to be change?
    Thats a head gasket
    Yes, if your oil is white or milky looking you have a bad head gasket that is letting the coolant into the oil. You should not drive it anymore until the gasket is replace and the oil is changed.
    It could be a gasket or even a cracked head or block. You might pull the spark plugs in the morning before you start the car to see if any has a water drops or rust on them so you can find what cylinder is leaking. It could be an intake manifold gasket that is leaking. Did your car ever boil over? Bad sign.
    Can be from the intake gasket also. If the motor is a V configuration.



    You have to check with the coolant also. Are there oil in the coolant. Is the coolant foamy. Do you smell exhaust in the coolant.



    There is also something they call a 'leak down' test(blowing air into the cylinder and hearing where the air it coming out) that can show where it is leaking from.

    Is there a way of telling if the head on a 1999 sunfire is warped without taking it to a shop?

    I am going to challenge changing a head gasket and need to know what to look for. thanksIs there a way of telling if the head on a 1999 sunfire is warped without taking it to a shop?If the engine has been severely overheated, the aluminum cylinder head may be warped. As long as you're taking it off the car to replace the head gasket, why not have it checked out by a local machine shop? Call around and ask what they would charge just to gauge the head.



    If the head is warped, but not too badly, you'll face a decision about whether to have it milled to make it usable again. This is called %26quot;decking%26quot; the head. It can affect the engine's compression ratio, although a mild decking shouldn't affect it beyond the computer's ability to compensate.
    Is there a way of telling if the head on a 1999 sunfire is warped without taking it to a shop?
    if it an alloy head it has to be skimmed if you dont have it done thers a very strong chance the head gasket will go again within days
    Is there a way of telling if the head on a 1999 sunfire is warped without taking it to a shop?
    most all the time you will find that you need a new head ..is there water in the oil? this wiil make the oil turn into what looks like a coffee milkshake,a sign of a cracked cyl. head,if there is just water/antifreze disapering,and or steaming out the exaust,you may get lucky and just change head gasket.to see if the head is cracked look for hairline/extremly small cracks between valves.alum. heads will crack even when the car has only overheated one time...good luck!
    with all the work involved have a machine shop check it...
    If you have over 80,000 miles on the motor you should have the valve guides checked and the valve seals replaced anyways. You only need to put a good straight edge against the head to check for warp using a feeler gauge.I resurface a head if it's .004%26quot; or more warped.It would also be a good idea to have the head pressure tested to see if there are any cracks internally. Do you have a torque wrench and know how to torque cylinder head bolts? On many vehicles you must replace the head bolts. Replace the thermostat if the car overheated as a precaution.

    You also need to clean out the holes in the block where the head bolts go, if there is oil or water in the holes from when you remove the head the head bolts will not torque correctly and all your work will be for nothing.

  • Any one have any knowledge of Blue Devil head gasket sealant?

    I drive a 98 firebird 6 cylinder and my head gasket recently blew. im really tight on cash and i was wondering if any one has experience with Blue Devil Head gasket sealant. Id like to try it out, but i was wondering if it doesn't work what will it do to my car. Can i just flush it out or if i try it and it doesn't work will it leave my car unable to change the head gasket? I guess I'm asking, If i use this, and its unsuccessful, is there any residue that i would have to break the engine down to get out before being able to change the gasket? thanks all.Any one have any knowledge of Blue Devil head gasket sealant?I used it back in February.On the day I lost the gasket,I had bubbling in the expansion tank and it had leaked so much coolant into the cylinders that I had hydro lock and couldn't crank the engine.Once started it was like a fog machine.There was no way I was going to replace both gaskets on the engine(V6) .They claim a 90% success rate with a money back guarantee.I have over 2000 miles since using this product.I am not losing coolant and the recent oil change looked good.

    The stuff looks like window cleaner and contains no fillers.It is important to remove as much coolant as possible along with removing the thermostat.Just to be safe I also by-passed the heater core because of horror stories I've heard.It is not supposed to restrict or clog the system as it has no fillers.I believe what is supposed to happen is when the BD hits a hot spot such as the cylinder gases leaking into the jacket,the water in the solution will flash off and the sodium silicate will be left behind.How it works against the cylinder pressure I couldn't tell you.This is very similar to the liquid that car dealers would pour in your crankcase to seize the engine during the cash for clunkers program.This product was recommended by a local garage who said this stuff works.If your going to build the motor or if the vehicle has low miles or is newer,then tear it down and rebuild it.But,if you want to save a few dollars try the BD.

    Good Luck.I did put a short video on Youtube.:http://www.youtube.com/watch?v=gCrUb8AXLvY

    Blue devil is a good cheap fix and is guaranteed to work when done correctly. I have done this for a few customers in a pinch, but remember when you want to repair it the right way you must do a complete tear down and rebuild but its cheaper at that point to buy a used engine and do the head gasket before the install.
