Oil Pump Failure? I have been hearing a new odd noise from the passenger side of the engine the last few times I drove the car. Today a friend and I were listening to it. I shut it off for maybe 10 minutes and when I restarted it there was no oil pressure. What happened? Did the oil pump fail? If so, could I have been hearing it going out?

when that happened to me i had erratic OP readings on start up but they evened out, never had any weird noise. but one day i just cranked my car up and it had 0 OP so i killed it and towed it to my mechanic. they checked it out and sure enough it was flat lined. out came the stock pump for a melling hv.

Or is this actually an engine problem? It seemed to be running normally though. The sound is hard to describe, kind of a rattle/knock like something is loose. What happens when you spin a bearing?
That is a common noise associated with spun rod bearings . Does the noise get faster and not change volume with rpm increase ? If so , most likely rod bearing . Good luck.
