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.
no as long as you are sure which side/head is leaking
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.
