The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

exact problem has occured twice first used oem replacement gasket set. it also began leaking after about 20000 miles. I had it replaced again. This time old school race car driver and motor builder used same gasket set but also used black sealent that they use for sealing windshields inside rubber molding. 80000 more miles and no sign of leaks. he has fixed dozens of these trucks the same way. he swears by this stuff and so do i now.

Intake gasket was leaking unknown to the "genius" mechanics who fixed my antifreeze leak. Drove the truck another week and the motor blew. Had to replace motor with a new one.

This is the second time, since I bought the truck new, that I've had to replace the intake manifold gaskets due to coolant leakage. The good news is that Fel-Pro has realized that their manifold gaskets suck and redesigned them. No more plastic with silicone sealing material. Hoping that they fixed the problem that the Chevy engineers created. Maybe they'll come out with a non-plastic distributor next. We can only hope.

Mysterious water leak discovered. No visible signs. No water on the ground. Recently discovered that it is likely the Intake Gaskets, poor plastic design. Will repair soon.

My 1997 c1500 just recently developed the problem of water in my engine oil. The mechanic said I had a head broken head gasket and it would need to be replaced. The engine makes a 'clacking' noise when I run it, so I have not repaired it or driven it much since it developed this problem. Anyone know what it will cost to repair this problem?

Coolant was leaking from intake manifold @ 450000 miles. I removed the intake manifold replaced the gasket,replaced the mainfold and changed the orange coolant to green. The orange coolant causes lots of problems with aluminum and pot metal parts in the engine cooling system.I have since swapped the original engine because of valve train problems.had to change out heater core,was leaking.Block Assembly(crank,pistons still in good condition even after 530,000 miles,cylinder walls still have crosshatch pattern barely any ridge at TDC)Swap engine only had 60K or 80K so should give me another 400K of engine service.Replaced Man Trans 3 times. Same rear differential.
