When observing the return oil flow (pulled off the return line on the oil tank) the oil flows /pulsates out when at idle, but when the RPM increases to 1500 or above the flow almost stops, and after a while the no oil alarm goes off.
I've checked the oil lift pump and pressure regulator and everything seems to be ok, diphragms, check valves and everything. Both supply and return oil lines are unrestricted.
When running on WOT (over 5000 RPM) the oil flow is increasing and I get no alarm.
Any ideas what could be wrong?
