Ken, glad you mentioned this. Case in point, one of my '33/34 buddies', had a situation of LARGE amounts of oil coming out the rear. Like a quart in less than 50 miles. The reason... the babbitt had 'gone-away' on the rear main. There was HUGE rear main clearance. Amazingly, the engine sounded fine and ran good.
