Actually, have to admit i didn`t measure after the last trip to crank grinder. Anyway, The oil pressure was good after i put it together (70+ psi) but dropped after the trip to the strip. If all bearings check out, could it be the oil pickup tube which i found at teardown to be a bit loose at the pump end threads, and suck air threw the threads? What do you guys use for sealant at the threads if any? i thought of a tack weld to lock it to the pump but that won`t seal it all the way.
