With the borescope I could see some scratches in the carbon on top of the piston, from the coat hanger search. Could not see anything from the dowl rod squish. One of the concerns in the back of my mind, was if the dowl rod became a "live coal" that the engine would diesel and not shut-off. Not sure if that could actually happen, but part of the reason that I did very short runs, followed by cool-down.
The new air filter didn't make the delivery today, so won't get in a full ride for a week or so. I always try to follow-up on my threads, and will do so.
