What started with my timing belt starting to shred itself has turned into so much more. Something in my gut told me to pull the motor cause something was wrong, and I’m glad i did. Pulled the oil pump to find the drive gear was so scored it left material in the front case. The balance shaft delete was an old balance shaft cut off and welded, that had some wear marks, but nothing like the drive gear. The motor never lost oil pressure as far as my Glowshift oil pressure gauge has showed as well.
I dug more and started to check piston 1 and 4 bearings and this is what I found. Both sides of the rod bearings in both cylinders are pretty the same way. The pictures attached are from cylinder 1. I noticed the slightest bit of heat marks on the crank. The cylinder 1 rod cap was hard to get off compared to cylinder 4s.
Realistically, what are my options. Plastigauge, and send it with new bearings, or pull it completely apart and get everything cleaned and machined? It has an eagle crank, eagle rods, and JE pistons. Motor was bought second hand from Performance Partout but bearings weren’t like this before it was installed in my car. I’m about ready to just send the rotating assembly to the machine shop with the original block from the car to get put together. But I’m to broke for that at the moment.
I attached the pictures from the belt being shredded to how it sits now. None of this explains why my belt was being thrashed, but I’m glad I dug into the motor. Seems I caught things before it decided to window the block.
