I was trying to rationalize in my mind how No. 1 cylinder wound up with 0.022" clearance between piston and cylinder wall? If all cylinders are measuring correct diameter for +0.060 overbore how did that piston wear enough to give 0.022 clearance? Or did maybe that piston start out undersize from the begining? Just wondering.

None seemed to have excessive movement.
