Just got my rebuilt engine out of the shop it's showing low oil pressure. I bought the mechanical oil gauge and its only showing about 4-6 psi. Ive already dropped the oil pan and the pickup tube looks good. I'm starting to think its the oil bypass? Anyone have a diagram or some advice to help me troubleshoot this problem?
Thanks in advance
Right beside the oil filter on top of the housing is a cap, take it off and it's probably spring loaded. It's set at a predetermined height to allow proper oil pressure. Make sure the plunger moves freely in the bore. The oil cooler is behind all this bolts behind the oil filter, remove the filter and remove the cooler. I guess somehow check for restrictions through the cooler, air?
Just spring and plunger, it looks like oil comes straight from pan to pickup tube to the pump. A crack in the tube ? Then it goes to cooler to the regulator, and eitherbgoes back to tank if pressures to high or continues to the filter. Where's your gauge hooked up at?
That would definitely be my next suggestion! Ive been looking at the lube chart as we were back and forth and I would think it's possible. If not you would have to have an internal leak returning back to the pan before the cooler? Not very possible unless your pickup tube is sucking air and not priming? Good luck
