Intake Manifold Gasket May Leak Coolant or Engine Oil on Pontiac Grand Am

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.

2000 Pontiac Grand Am - 3.4L V6 14,523 mi,
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.

I have oil (or is it coolant) leaking over my two front tires and have fixed the intake gasket everyone is talking about twice. My garage floor is swimming in whatever it is that is leaking. I am fed up. I hate to get rid of my car because this is the most dependable car I have owned since 2006. I have been told by the mechanics that this is a long running problem with the grand am. I am ready for a trade in but worry that I will buy something with worse problems than this. The last mechanic reported that many bolts were missing and he didn't even bother to replace them.
