Bent rod, bad piston, wrong piston?

Hope it wasn't a rag in the intake tube. ;)

My official guess is some issue with the piston.

I would agree that the wrong piston maybe a possibility, cant really think of anything else that a leakdown test wouldnt show.

If no marks on the piston/head then fuel or water hydrolock?

If this were the case I would guess there is a repair order somewhere for a new injector.
