... to me the oil pressure seems to be very high, especially with 10W30 oil. I've seen some references to a 50 psi relief but mine must be higher. I don't know what oil pump was installed or if the relief was changed. Any thoughts on this?
if your engine is fitted with an external oil line from the front port near the oil filter to the rear port on top behind the intake, your pressure will read higher than without the external line. also if your gauge sender is connected to the front port near the oil filter you'll be reading direct oil pump pressure rather than from the rear of the engine after all pressure losses
reading direct oil pump pressure turns the gauge into more of an idiot light because you'll never know what the pressure is at the far end of the engine, just that the pump is working or not
