While I'm not a full on diesel mechanic. They just teach us the ins and outs in case one of our generators breaks at sea. That is exactly what we do. Hook it up to the inertial dyno, start it, check over the basics, then run the piss out of it.

Before we rebuilt our engine. We had to get a baseline dyno run. Our engine upon pre-overhaul run up seized up #1 cylinder and #4 was close. All because the oil jets for the skirt cooling were plugged.

We replaced those power packs (piston, liner, rings and wrist pin) reassembled it, then put it back on the dyno and ran the piss out of it. Keeping in mind though, that every single component was gone over with a micrometer/dial gauge/feeler gauge to make sure it was fully in spec.

It didn't have a single problem except for loose wires on the starter that sparked a good bit initially.
