Milodon oil pan what is correct gasket to seal it to rear main?

Well water is the problem! In California they can't use solvents to test for leaks. Water doesn't travel like solvent or hot oil does..
ok let it sit full of whiskey, i don't care sommabitch sure as hell wont hold oil! The best part is waiting until you've got it in the car and all your **** rigged up to find out she leaks.
