Oil pump problems
Every time i used to start my motor the oil pressure would jump to around 40-50 psi. But now withing a weeks time (200 miles or so) it barely gets to 10psi on cold start ups. My question is can the oil pump fail this fast? Or could it be the sending unit going bad. I have no problem replacing the oil pump but if i dont need to then i dont want to. The PO said this motor only had 20,000 miles since being rebuilt but im not 100% thats true.
