Intake Manifold Gasket May Leak Coolant or Engine Oil on Chevrolet 1500 Pickup

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.

Started smelling antifreeze around the truck, looks like it is pooling up around the base of the intake manifold area ........... My understanding is that the ORANGE DEXCOOL antifreeze is eating up the factory installed intake manifold gaskets. How could GENERAL MOTORS get away with this kind of issue ? The same problem on almost all GM cars and trucks that use DEXCOOL coolant.

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.

I have had to have my intake manifold gasket replaced 3 times already with only 113000 miles on engine. Is there a recall on it?

My intake manifold gasket was leaking. I did a repacement of the gasket. I replaced the gasket myself nad the cost was around 12.00 dollars. It took me about 6 hrs to complete job.
