Dod oil pressure relief. Maybe re-read your proof because you aren't understanding it lol. Raising the engine speed to above 1000 rpm causes the oil pressure to increase to about 45 psi. It gets about 35 to 40 on cold start, and it has gotten as low as 5 (according to scanner) after driving for a while and checking it. Read on to determine the cause of the low oil pressure symptom.

If there is low oil pressure, AFM lifters will not properly work. If the engine speed is increased even more, oil pressure tops out at about 55 psi. I would highly recommend you read that guide first before proceeding further. If the filter screen is clogged, it will restrict the oil flow to the oil pressure sensor and will indicate low oil pressure. If the valve is stuck close, an over-pressurization condition can occur, causing the filter to become distorted or the gasket/seal to dislodge. 814-M14-KIT comes with a M14x1.
