I am replacing a leaking oil pan and gasket on my 2000 firebird with the 3.8L. I have a new oil pan and the fel pro plastic gasket with the molded rubber in it. With all the work I had to do to get the pan off I really don't want to do it again, I want to do it right the first time. So, looking at the gasket, having a hard plastic gasket with a small amount of rubber seal around edge doesn't seem like a good idea to me. I know some permatex should be used in the corners, but still that's how the factory gasket was installed and it leaked, bad. Would it be better to add a very small bead of permatex around the whole molded rubber seal as well? Is this a good idea or not? If so, what permatex should I use? I have the ultra black already, but I've heard the ultra grey is better?? Thanks.
