Are the pump and injectors original? Sorr I have missed alot of the thread.
I have seen a 3306t in a d7 have a injection pump isue and a day later spin a rod bearing. And a have personally seen a cat 966b toss a rod then have a rebuilt engine dropped in with the same pump and have the same cylinder lock up. That one was never solved and the machine is still sitting. Maybe they screwed up on the rocker arms. The owner gave us the machine but I haven't gotten around to hauling it. I've also witnessed a burnt cylinder in a old d7e 48a after a injector cup unscrewed and washed the cylinder during operation causing a piston failure.
Anyhow just tossing it out there not saying this is the cause but you never know.
