I had a 95 Chevy truck like ours.When my heads started to leak I noticed the oil got real milky/brown from coolant getting in the oil. I removed the heads and found out the 350 Chevy motors will start leaking on the ends of the heads when the motor gets a lot of miles on it. After fixing it,I gave this truck to my son and now it has over 300,000 miles on it and still running strong! You can get a leakdown test done to see how tight the top-end is.
you shouldn't have to change them unless they are leaking, blown, or you take the heads off for a repair or rebuild
if you had it heat high enough it very likely worped your heads and or damaged the head gasket
Leaking what???It is not common for a head gasket to leak. I would check all 4 corners of the intake real CLOSE for antifreeze and oil. I mean close.If oil sending unit,are the back of the intake is leaking. oil will run down around the heads and make the heads look like there leaking. Make sure you look at the back of the intake real good.
Remove the cylinder heads from your Chevy engine. Remove the head gasket and clean the head gasket surface. Put the new head gasket on and reverse the process.
That means you have WATER leaking into the combustion chamber. BAD head gasket, Intake gasket leaking into the cylinder heads ( NOT COMMON ) Head cracked in are around the valves / from overheating. More then likely you will find your problem in in the head gaskets are heads.
About has to be. Very unlikely to be a head gasket.
yeah, but it might blow a head gasket, i wouldn't chance it
Sandwiched between the heads and the engine block.
replace the intake gasket set
Cylinder heads are installed on a Chevy 454 big block engine by placing the gasket down on the engine block and positioning the heads over the marking tabs. The bolts are then installed and torqued to specs in sequence.
A blown head gasket means the seal around the cylinder heads is leaking. It will leak oil and over heat until the engine seizes unless it is repaired.
If a 1995 Chevy Cavalier overheated and will not start, try checking some of the sensors near the radiator. The radiator could be leaking which caused the overheating, and in turn, caused a sensor to get wet in the engine compartment.
From 1996 to late 1999 There was a problem with the intake gasket design on the Vortec engines. They have sents redesigned the gasket and now it does not leak as often. Intake Gaskets leaking is a common problem. Now the only time you have a problem with the heads is when the engine is over heated, and I mean HOT. Then the heads warp and the head gaskets leak or blow. Chevy just don't have problems with the heads on the V6 and V8 engines.
no as long as you are sure which side/head is leaking
are you sure its just a blown head gasket?... if heads are warped due to overheating replacing the gasket wont help you will need new heads as well. You can get a Haynes Manual or Chiltons, they will give you step by step guidance on replacing your gasket.
does anyone know the torque for cast iron exhasut on aulm heads ..small Chevy
A head gasket does not wear out and there is no specific reason for replacing one unless it fails. Usually, head gasket failure is related to engine overheating that causes the heads to warp. Thank you, but it's not the head gasket that has broken. I had the seal replaced last year because it was cracked/leaking and leaking oil. And now the garage says it needs replacing again. Should it been leaking again so soon (after 13,000 miles)?
You will need to remove the intake and the exhaust manifolds and then you can remove the heads to replace the gaskets.
IF BOTH HEADS ARE REMOVED ABOUT 900.00
That depends on how extensive the problem is, if it is just leaking externally it is cheaper to replace the gasket. If it has severely overheated, the heads can POSSIBLY be warped, but even so may be able to be repaired. If the coolant got into the oil and was not noticed for a considerable amount of time, internal engine parts can be severely damaged which would warrant engine replacement.
yes, you have to take the engine out of the frame. there are good videos on youtube of how to remove the heads/jugs/etc if your gasket is leaking, you might try re-torquing the heads first though which might fix it. you can do this with the engine still on the bike but you have to remove the gas tank.
noNEW ANSWER: Sorry but the above answer is wrong. The only thing that is different on the 400 heads is that they have steam holes in them and it don't matter if they are blocked off by the head gasket. And YES they will bolt right on the 350 block with no problems.
The antifreeze in the oil is a dead give away that the head gasket is blown. Make sure you send the heads out to be checked so they are not warped.
