Dude how many people on here have told you the intake manifold gaskets on these 3800's go bad around 70 to 80k? Get the lim gasket fixed and join just about all the rest of us with high mileage 3800's with aftermarket lim gaskets. Every 10 year old car will have something that needs replacing. If you want zero problems lease or buy a brand new car... Even then you will probably need warranty work done in the first three years. Sh#t happens.
