The engine (Perkins 4-236) was rebuild about 100 hours ago and at about 10 hours the light did flash on , shut it off and restarted and all was good.
Now at 100 hours the light will go out when started and remain out for bout 20 seconds then flash on.
I pulled the sending unit and inserted a mechanical gauge and when started pressure is 60 psi for about 20 seconds then drops to almost nothing.
If I let the engine sit for a time the process will repeat itself
I am leaning towards a faulty oil relief valve but would appreciate any advice or ideas before I pull the pan.
