I have a 400 gas start diesel. The engine has about 300 hours on it since a complete, out of frame, overhaul by me. My third one of these types of engines. Nothing was omitted during this event.

I have torn it apart to find that the wrist pin bushings have failed. The holes in the bushings appeared to have been properly aligned with the oil gallery in the connecting rod. I can see nothing that was assembled incorrectly. I know this is a high wear area for this type of engine, over the long term, but does anyone have any ideas why these failed so prematurely?
