12 lbs at idle? spinning it with a speed handle should have more than that .All the new syle engines only use 5w30 and prostocks use 0w oil. In all my old style engines i keep the mains at .002 to .0025 and the rods at .0015 to .002 max. What were the bearing clearances? A volume pump should still have a normal bypass spring in it so it still should have 30 to 45 lbs idle pressure. U might check the bypass in the oil pump and see if it is hung up with a burr or not. I still like to see at least 15w40 or 20w50 in an old style engine. I would pull the pan before u have a bearing go away and at least confirm the cond of the mains and rods. if u say u have a noise down their,even more reason. what brand of pump is it? Hope u find ur trouble.
