I have about 1000 miles on this engine since putting new bearings, crank grind and new cam in. I am using the exact same oil pump as I did before this work but now my oil pressure is quite a bit higher than it was before. The motor had about 20,000 miles on it and the crankshaft broke which is why I redid bearings, crank, cam, etc.
I started out running a bronze distributor gear and when I checked it after 1000 miles - it had considerable wear.
I replaced it with a cast gear that was in good condition.
I am looking for feedback on whether I need to pull the pump and see if the pressure relief valve is somehow out of adjustment (are they adjustable?).
When it is cold, it pegs the oil pressure gauge and when warm, runs about 40 - 45 psi at idle and pegs it at anything above 2000 . . . running Delo 15W-40
It was suggested to add another oil pressure gauge to verify that mine was accurate and other than the new gauge being a lot slower responding, the new gauge does indicate that the pressure is higher than the in dash gauge can show.
