I've been told that oil pump's are known to give out often on RB 's so this is definitely one possible peoblem, The car is parked until this is figured out.

If he can source a new OEM sensor, tell him to get it
Oh yeah, my statement is only true if he's getting the readings he is talking about from the stock oil pressure gauge in the cluster. If he's getting those readings off of an aftermarket gauge, then it's another problem

This is another possible problem we're considering since I've also been told that the sensor is another possible culprit. He is using the OEM guage on the cluster, so maybe upgrading to an aftermarket guage would't hurt?
