Grand Prix GTP 3.8L

This car has put me at my breaking point, literally I am broke and can't afford to fix it anymore. First I replaced the valve covers because of the fire issue, then while doing that I saw that evil milky crap in my valve covers. So I replaced the LIM gaskets after hearing about that issue, and the PLASTIC was cracked. Now a week later the milky crap is back and i have now discovered my head gasket is blown too. GM has lost my loyalty after this. I never did anything to this car that would cause all these issues. I personally repaired all this stuff myself and am still out a lot of cash.It just kills thinking after all that crap I did replacing the PLASTIC LIM gaskets i have to do again and some more to replace the head gasket(and of course its the back one).I am a buy American be American kind of guy but after this I think it is safe to say I will NEVER buy a GM product again.
