I’ve not used rubber ones. Might give them a try. I’m going to get to that test!

UPDATE: I couldn’t get bubbles but could hear air coming from the seal area. I boosted the pressure to 10-15 lbs. air is blowing out the right side of the rear main seal. Not the left, just the right, which makes me wonder if it is the seal halves leaking where they meet.

Advice?
