My D8N 9TC02252 was getting exhaust in the coolant. Pulled the head and the head gasket fire ring was blown out on #6. Sent it it to be resurfaced, magnafluxed and valves replaced.
The liners had no crosshatch left so we were hopeful of getting away with an inframe. We dropped a rod and a main cap and the bearings were pretty rough and the crank had a few minor scratches so we decided to do a complete rebuild. Still waiting on word on the crank. Hopeful for just a polish.
Just looking over the oil pump gears and they have an abnormal wear pattern to them. This has the two section pump setup. The rear 1/3 to 1/2 of the gears in the main pump body have more wear than the forward portion of those gears. The scavenge pump gears appear to have more uniform wear. I can still see the machining marks on the gears except for where they are polished. They are smooth and look good otherwise. Just wondering if the abnormal wear is anything to be concerned about?
Also seeing as I have the torque converter out is there anything I should check or replace on it while it's out? Was running good when we took it down. It's my first time dealing with one so I'm a little unsure.
First pic is of our fun so far. I think we reached the end of our troubles hopefully. Second is a scavenge pump gear. Third is a main pump gear. Fourth is a rod bearing. Think we were on borrowed time.
Thanks
