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 hit the nail on the head, on the way to the track we got off the e-way and the truck was HOT I got on the throttle to blow the carbon out after the extended cruise, it rattled and I didn't lift as quick as I normally do. I'm sure that's when the I poped that chunk loose. I should have known it would rattle after the hour or so of 70 mph at 34-3700rpm. Live and learn I guess.
