I have a 2003 Universal M3-20B on an Ericson
30 that I recently purchased.
Last time out, noticed that the oil
pressure readings are 85-90 psi and don't fall as the engine
temp is fine and engine
runs great. Based on reading, I tried to access the pressure relief valve at the filter. Changed the oil
, removed the filter. Can't figure out how to remove the valve for service
but the ball moves freely.
Replaced the filter and restarted. No real change.
With the engine completely cold and not yet started, the oil pressure reading is 35 psi before I even crank the engine (meter reads 0 with the ignition key off). After starting, the pressure rises up to ~85 and stays there. The pressure before even turning the oil pump
doesn't make sense to me. Starting to think that the problem is with the pressure sensor.
Anyone ever experienced this? Any suggested solutions? I am trying to figure out if it is safe to run the engine.
Thanks for your advice.
