It's all just speculation not seeing the engine for myself.

- What I saw of the pistons they had no valve/piston damage. Timing chain looked normal as well.
- The engine idled fine even with all this damage. Maybe a bit of smoke but nothing to write home about. It simply lost power and sounded bad.
- In the last 6 month it threw a lot of emissions codes, and went into "regeneration" mode quite a few times. Regen is when the brain detects excessive back pressure in the particulate trap, revs up and dumps raw diesel into the trap to burn it out. The turbo had a bit of oil residue on it that the pros said indicated that it needed re-sealing - which we did. Another expert, however, said that since there is not crankcase vent on these newer diesels that all the turbos get oily reburning the crankcase gasses.
- While I've owned it the oil has been changed every 5000 miles on the dot. But I bought it used.
