Cold (say 40F), my oil pressure goes right off the charts as I spin the motor up. I don't mean redline, we're talking 3500rpm. My personal arbitrary comfort limit is 105psi, which is ~2500rpm when the motor is just waking up. Once it's warm, max pressure is 90ish, right about where it's supposed to be, right? Steve at Arena put a mechanical gauge on it and he confirmed the behavior. He's going to dig into the oil pump and check the pressure relief valve. The working theory is that maybe the valve is binding up a little. Curious if anyone has seen this before. Any BTDT info I could send Steve's way would be great. Random details: '01 360. 24k miles. Redline 5w40 changed yearly.
