Let me assume that it is possible that pieces of bearing swarf are all through the oil system right up to the filter, and the filter either has a bypass or it does no have a bypass. If the filter has been plugged it may have bypassed debris right on through the system contaminating the rotors and other bearings. If the filter has no bypass feature, but has been packed with debris, it may have collapsed and allowed debris to run on through and ruin eveything. It happened to me. Like the corner seals, the pump parts are made of powdered metal and have very little strength. Scrap the pump. Pack the new pump with bearing grease.

 

Remember a Fram filter and no filter is the same thing. Friends don't let friends buy Fram filters.

 

The pressure regulator only affects peak oil pressure. It has nothing to do with oil pressure below 115 pounds. If it is the current valve is the old style that can be disassembled, just take it apart and clean it. Check cracking pressure with the shop air supply. The FD valve (welded shut) is set at 115 pounds which adds complexity to turbo seals and drainback problems. You would probably want smaller jets in the crank spray nozzles as well.

Race engines use between 85 and 100 pounds which is plenty. Never an oiling problem.

 

Take it apart. Take the pieces to the car wash and run 5 dollars through the plates and rotors. Take the oil lines off and the cooler as well. You are getting so good at this you can do it all in one day. The next build will be a keeper.
