Well so far I've changed my oil switch and the oil pump. I've blown about a thousand bucks and yet my oil pressure light still comes on when I'm at idle or low RPM's. This sucks. Now I hear that probably the only thing left that it could be are the bearings. How much does this cost? I don't use the dealer. I refuse to spend 100 an hour labor. I know a good BMW mechanic that charges 70 an hour. Why would my bearings be shot at only 77,000 miles? Is anyone familiar with bearings and oil pressure issies? My oil pressure is at 5 PSI at idle and 38 PSI at 3000 RPM. That's low but not extremely low.

Are you sure the pump you got was good? I mean, did you have the same pressure before *and* after the change? Sometimes replacement parts aren't good either.

But my gut tells me you have other, bigger issues. Was the car ragged on at some point? If damage hasn't been done yet, putting in new con rod bearings isn't that bad of a job. On most cars, it can be done with the motor still in the car (from below).

Yeah, the pressure was the same before and after the new pump. So new rod bearings is about the same labor as a new pump?
