You butted the rings which blew the ring land off. Your end gap must have been correct or close to run 25,000 miles though. You were running hot with borderline fuel or just didn't lift when it was rattling. Was your top ring @ .026-.028"?

You won't beat the Mahle's with their tighter than normal clearances for a forging. J.Rob
