Oil psi issues Have a Thompson motors 416 with a Magnuson 2300 over driven. Been having low pressure almost since the initial crank up. But now it’s dipping under 10 psi hot. Pulled the pan found a sticker stuck in the pick up. Reassembled still the same problem no change. And have also tryed different weight oils same problem

Check to make sure your o-ring is good, and not pinched, and the pickup tube is seated properly. The pressure relief valve in the oil pump could also possibly be stuck, but i doubt it if it's new (but check it out)... If these things check out, then I would guess that you already damaged your bearings and now your oil pressure is low because of your damaged bearings. This exact thing has happened to me before. My mains got trashed, and i did a rebuild. Since it's so early, you could probably take the engine completely apart, hot tank the block, put new bearings, and send it if you didnt damage your rod or main journals.
