I’ve been messing with this 3306 cat for a week or so on and off. I did a full rebuild with all new consumables on it 3-4 years ago and it sat for a year or so before we sent it to the field. Once there it ran great but started loosing oil pressure after a few weeks. We ran it an entire summer before the pressure got low enough we couldn’t run it anymore. I had 2 spares at the time so we swapped another one on and it’s been fine. We used the other spare up right after Christmas so it was time to tear back into this one... I pulled it a good ways down leaving only the head, complete valve train, and rotating assembly in the block. Turns out the oil pressure relief on the then new oil pump was never torqued down at the factory. The bolt backed as far out as the pump housing would permit. Bearings and internals still look brand new. Slapped a reman cat pump in it and start sealing her back up. Just glad it was something simple. Sucky part is that’s just one more part im going to have to inspect going forward. Here it is ready to come off my engine stand. Pardon the mess below. You never can get all the oil out before you pull the pan.
