Not the ones on the bottom of the tray holding it on, but the ones underneath those that set the position... I think that put the tray in the wrong position and helped cause the pressure on it to break... I would have set them lower so the pan could be tighter to the crank, from what I see from the pictures....
What else caused the pressure on it to make it break???
Makes me wonder about the balance on that assembly. I also suspect the main caps are walking around in that engine. 10 years is a good run so, maybe metal fatigue is to be expected?
