Dad's 360 Ford returned it to the sump when he lost a galley plug. No oil pressure, plenty of perfectly good oil in the sump, clattering lifters was the main symptom. Let's hope yours is just a bad reading instead of low pressure. Oh, I thought of another way to kill oil pressure. Loosen the bolts on a cam bearing tower so the oil comes out between the tower and the head. Mitch.
