Can anyone tell me whats going on with my motor... I start my car cold and my oil pressure light stays on till a little warm then I'll drive it and it starts to flash after about 3k, but once the engine is completely warm it wont come back on
 
Considering that we all run on low oil pressure, because that is just the way it is on a 420a. You should put a gauge on the backside, where you can get a correct reading to see if it is on the Electrical or Mechanical side of things. IE: Faulty "Oil pressure switch/sensor/sender" or possible wiring issue has occurred.
