Just a quick question regarding oil pressure.
i took my car off the road for 6 months its an s13 ca18det, before i took it off the road my oil pressure was roughly 5bar when cold and settled around 2bar at idle.
Now my gauge only reads just over 2 bar all the time.
i have checked the grounds on sender and gauge and have changed tbe sender for a new one bit it has made no difference.
i am using 10w40 fully synth oil.
i have read about the pressure release valve on the pump and is there anyway of checking it?
The engine was rebuilt about 10k miles ago and a new pump was fitted.
