Problem Description and Possible Solution
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.

It keeps not wanting to start and its leaking oil onto my engine, the antifreeze keeps disappearing when i fill it up. and it over heats and shuts off while im driving.
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.
