Btw, I have another theory why your friends spun bearings a few months after new piston/ ring install.
Looking at the bearings, when there is no longer crush on them, and then are only sitting in the rod/ cap. It seems to me that oil might sneak into that gap while they're sitting. I plan to take all of them off, brake clean the back and the rod/ cap, install them dry, then do a light coating of oil on the bearing surface.
Any other bearing install tips before I start today?
