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.

noticed coolant on gound. kept adding coolant, sometimes twice a day. looked over engine compartment and saw puddle of coolent by manifold. clean area up, started car and found leak. Needs gaskets replaced. I called a repair facility was quoted between $1200.00 to $1800.00 to fix. Has Pontiac acknowledged this problem?

I had the Low Coolant light come on. Took it into the dealer who said I need new Header Gaskets. I am assuming I need Lower Intake Manifold gaskets as well. I've been reading that is a common problem with GM V6 engines as the DexCool coolant degrades the plastic gaskets. This is apparently a known GM problem. There was a class action lawsuit that was settled in 2008 on this issue. However, GM should do a recall on this issue as it is huge. I will never buy another GM car or American car for that matter.

I have had to replace my intake manifold gasket three times now, three years now. This car has been nothing but trouble since I got it.
car was leaking coolant, had to have intake gasket replaced. Leaked coolant again, had to have freezeplug replaced. continued to leak, was told the head gasket was blown. been driving it for about 2 years on blown head gasket.

Pontiac Gran Am GT 6 cylinder.my car is overheating and leaking coolant. I had the thermostat replacement and it is still leaking. I was told it was a head gasket but before I tear it apart I want to know for sure. There is no coolant in oil, no gas in oil. And it still has quit a bit if power. Any ideas?

I have a 3.4L V6. Just bought it as my first car and immediately found problems going through Coolant quickly. It was leaking out from under my exhaust manifold, but I couldn't pinpoint the exact spot. White smoke/steam would also roll from under my hood while driving along with incredibly high engine temperatures. I suspect a blown head gasket. GM should absolutely have a recall on such models with this problem.
