NO 105! Use Lucas Assembly Lube. Use 105 if you like to go in there later and find white junk all inside your engine. I quit using that many, many years ago. Lucas works well, sticks to parts better and doesn't leave any residue or debris after startup.

I don't. Clean the cylinders with WD-40, then re-clean them using ATF and lint free towels until no metal is picked up on the towel. Put a couple of squirts of motor oil on the ring pack and rotate the ring pack to work it into the lands. Set the top and second ring gaps 180 apart, then install. No need to load the cylinders up with globs of oil.
