I'm having an issue with a new Stroker built '06 4.0. After the engine gets good and warm, I lose oil pressure, at idle, and my check gauge light comes on and beeps. I can get the pressure back if I heal and toe with a little throttle. I read the threads of other Jeepers similar problems, "replace the sensor", which I did. "OPDA" (Oil Pump Drive), which I replaced, and still no fix. I also read on a different forum that high volume oil pumps (which I have) should not be used on stroked engine. I also have a ticking sound I can't pinpoint because it only happens under load. I noticed the OPDA that I pulled started to have the teeth on the gear wear down bad and I only had a couple hundred miles on it.
