Didn't see this till is a 96 5.7L vortec; I believe it is a one piece rear main. Not 100% right now.

It isn't pissing out; I did an oil change a couple weeks ago but the oil isn't low or anything yet. It is not leaking a lot but it is leaking.

I will try the pro seal; and I believe I am going to switch to rotella 15w-40; I've read a lot of good things about using it and I know a few people that run it on 200k+ engines and have always run it.
