-- [ From: Herb Sloane * EMC.Ver #2.5.3 ] --
My C-85 engine with approximately 650 hours since (questionable) major indicates oil pressure no higher than 25 (on the line between yellow and green) at cruising altitude of 2500 ft. My mechanic has changed the spring in the oil pressure relief valve and added two shims. He has also reamed out the aluminum case where the oil relief valve fits for better seating.... all to no avail. I'm afraid to continue flying the plane for fear that the low oil pressure reading will cause permanent damage to the engine so my lovely ERCOUPE sits and waits for relief while I boil! Other than a complete major which is prohibitive at the moment can anyone offer suggestions for solving the problem?
