I had my E1 motor rebuilt a year ago, only got around to getting it going this week.
My problem is the mechanic that rebuilt it has done something to the oil pressure relief valve.
I am getting over 100psi at idle (this blew the oil filter gasket out). Took the sump off and found there was nowhere for the oil to return to the sump.
Drilled out 1 of 3 plugs going up into the 2 passages for the pressure relief.
Now with no spring or piston.. no oil pressure.. that is better. With spring and piston.. still over 100psi.
Question is does anyone know how the horizontal and vertical passages connect around the pressure relief? Which ones should be plugged?
(original mechanic can't remember).
