2004 Intake manifold deteoriating gaskets problem

we own a 2004 pontiac grand prix supercharge it has had the same problems that the 2003 has had that you listed about the gaskets NOW after having the upper and lower gaskets replaced the engine blew ( just a week after we got the car back) does this ever end??

Welcome to AF.

Your post has been moved to the Pontiac Grand Prix forum for any comment. Interesting a supercharged Series III 3800 engine having similar issues as the previous generation Series II 3800.

was it overheated?

And did your mechanic make sure to replace the throttle body coolant o-rings between the LIM and the supercharger?
