Nevermind, I answered my own question. Put grease on the oil pan and installed it to see where it left marks. Practically the whole side of the oil pan is missed by the gasket, except around the bolt holes. I'll post pics to show what I'm talking about.

Great idea, garbage execution. 0 for 2, junk mancini rear main seal and junk jeg's oil pan gasket.

One day maybe some one will start making stuff that actually works.
