What I would like to know is why it has had 2 sets of pistons and liners in only 550k miles?. Something does not sound right at all if that is the case.. and was all OEM parts used?// was a new head used?... were the liners raised to 0.015"?... and did anyone double-ensure that the rings were all set correctly (180-degrees away from each other properly) as the pistons went in?..


those are the things that come to mind when I read your post.
