Had someone pressurize a rebuilt engine block with the oil pan off to see where the oil pressure was going. Seems there is a small factory drilled hole in the oil gallery that sends oil straight back into the pan. Could be where all the pressure is going. Checked another block and it had the same hole. Engine still running years later. Don't know why the hole is there. Any bright engine builders out there know why? Have my guesses but want to here someone elses best guess. Diesel Dan (the pump man)
