I know it can be hard to keep the top of the rod clean when changing bearings with the engine in the car. Damn crank is in the way. The cap is easy and can be kept very clean and dry. So this is a good question.

I would think that the crush force and hatching on the rod big end bore would still hold the shell even if there was a bit of oil on the bearing back. It would be nice if one of the professional engine builders weighed in on this.
