I sat in on so many of Dart U classes back in the day.

Us marine techs would always have the topics and even disagreements about leak down tests and compression tests plus leak vs comp. Even many marine techs leakdown test 2 stroke outboards. I never did, we would pull the heads for those but compression check beforehand. Anyways this is a good one I sat in on years ago Dart U.

I actually like vacuum testing better
