Good to hear! That's what I had posted earlier, dual breathers solved my problem, and I made my own setup using a T in back of the Ram Air pan. Just a note, the breathers with those black 'loose fibers' inside are much better than the ones that use foam.

Those rear main seal leaks are sometimes a bear to find. When the crankcase pressure is high, the oil gets pushed out the rear seal, and the flywheel flings it over the starter, and the oil filter housing. By the time you jack up the car to look, it appears the oil filter housing, or the oil filter itself, was leaking.
