The article on rod side clearance is interesting.

By comparison, the 6G72 designed clearance is much tighter than 0.017" at 0.0039 - 0.0098" with a service limit of 0.016". Maybe that has something to do with why the factory used the rod squirter if the tighter clearance leads to a dry cylinder wall.

Dunno...... but you're probably right - in the end, I have to make a best guesstimate and see what happens. In the meanwhile, the more input information the better. Thanks!
