Lol Northdriver....I've always heard that Ford techs EARN THEIR MONEY!
But I've always had Ford trucks and gotten good life out of them up until now. Ironically, I shelled out the extra $$$ because I had heard that the earlier Ford diesels were pretty good and I have a friend who's 7.3 went to almost 400k miles without a major rebuild. (HIS problem was keeping the rest of the truck together around the still-running like a top engine!)
The piston is still in the block, just like the picture. Ford won't pay to diagnose. They just denied my warranty so that they wouldn't have to get their hands dirty and actually find the problem.
I'll keep the MAT and throttle plate screw in mind when I talk with them again. That's a BIG throttle plate screw thread diameter, if that's what it is! Otoh, the impression on the piston crown is BOUND to look larger than the object, just because it probably got pounded in the same place a couple of hundred times or more before it jumped over to another area...
The "foreign object left in by the tech on the previous repair" theory seems to be pretty popular. I just wish it was easy (or even possible) to prove! The dealership is trying to deny responsibility for ANYTHING, even though the tech has since been fired.
