Been having oil pressure that seems low. ~5psi at idle around 176F. My thought was bypass piston is stuck open or isnt working correctly. Opened up the oil pump assembly to see some scoring in the oil pump gears. Not sure how to check bypass piston but i disassembled it. The plunger/piston took some help to get out but it somewhat moves smooth. I already have a new front timing cover but i was hoping to find something that would explain my low oil pressure. You know what could low oil pressure? Ive already pulled the pan off to look at the pickup tube and couldnt find anything.
Thank you!
