I have a 99 GTP that I bought a month ago. After seeing and smelling oil on the engine and researching on the forum, I decided I want to replace the intake manifold gasket (still black), oil pan gasket and valve cover gaskets. They all seem to be suspect on these engines. My car has 110000 miles and I bought from the original owner who I have known for a long time. I know the car has been babied but none of these gaskets have been done. I am finding conflicting part numbers for some of the gaskets. Can someone share the numbers for the parts I need, preferably from one place? I have a friend who is ASE certified and has his own shop. I am going to help him and he's not charging me. I just want to make sure I have the right parts. Thanks in advance!
