Well, I don't know that I have the answer for you; but, when I first stuck the crate motor in my 55, I thought I was going to have to invest in a refinery to keep the oil in it. It has been a few years now (over 10) but I don't remember it taking 4 quarts after 200 miles while the rings seated!! What I do remember doing though was replacing the pcv valve and putting vented caps on both valve covers to try to get as much ventilation as possible to the crankcase. That seemed to make it bearable until the rings finally seated.

Lotso luck to ya,
