My brother just called me asking if 150psi on his oil pressure gauge is normal..... I really don't think that is. At all! This is him cruising on the freeway too. For reference, he has a built motor, with billet pump gears and a worked pump housing. My guess on oil is some form of a Castrol 10w-40. It is a very hot day today, in the high 30s. He's thinking it could be a faulty sensor for the oil pressure gauge. I'm not so sure. I'm gonna put a scanner on it when I can to see if there's any codes. Any ideas on this? Is this concerning? Could too much oil cause this? Link to comment Share on other sites More sharing options...

There is a chance that the pump has had this done and will be running all kinds of pressure...all kindzzzz. Otherwise it could be a faulty gauge etc. 3 minutes ago, k31th said: the oil pump didn't have a relief added to it Yeah nah it's part of the casting. You'd have hundreds of psi if there wasn't a relief circuit. That's why housing crack, cos the housing is subject to the pressure before it bypasses the relief circuit. 1 Link to comment Share on other sites More sharing options...

Second confirmation the gauge and/or sensor is I <3 Bananased, he turned the car to acc and the gauge was reading between 70 and 100psi. 🤦♂️ Link to comment Share on other sites More sharing options...

The parts were anodized so when I fired it up there was an oil light. Pulled the whole thing apart again to diagnose and ended up having to run a wire to earth to get a proper oil pressure signal. That was a couple of hours I'll never get back 1 Link to comment Share on other sites More sharing options...
