• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

I hope it's this easy

first off, before anyone says to search lol, i've been searching on the site for a while, found a couple things, but nothing concrete.

My DD is a 98 mustang gt, and I also have a 99 cobra in the garage, but I'm getting my parents 02 grand prix gt, completely stock with 85k miles, but the dealer says the valve cover gaskets are leaking and the "intake plenum leaking internally and externally" and was saying something about the coolant getting into the oil somehow??

the only way I know of is thru headgaskets, but i'm not that familiar with the grand prix's. is there a crossover on the lower intake manifold that would be able to cause them to mix or anything? I'm doing a compression test in the morning, and i'll put the results up in the morning

also are there any tips you guys have on doing this? or little tricks or problems that are normal that I should look for while doing this?

thanks guys, from what i've seen it looks like a great forum, and i'll be staying around if i can get the car fixed up finally.
 


Yes...Lower Intake gaskets. Get the ones from GM. Also, grab new coolant elbows and valve cover gaskets. There are coolant passages in the intake and the throttle body. If I were you since your yanking it all apart you might as well do everything...new plugs/wires/PCV/fuel filter...you know...basic full tune up.
 
I'm tearing it apart as we speak, and im picking up the gaskets in a little bit. thanks for the info, i got a top end gasket set from fel- pro that is in the backseat, but idk if i should use that.
 
Just for your reference the Part # is 89017825 for the gaskets he's talking about. Go to any pontiac or chevy dealer.
