How to change oil pump in 4.7 - 2000 Dodge Durango

Are you wanting to change the oil pump because the oil pressure flickers while idling after the engine has warmed up? If so change your oil pressure switch (located next to oil filter) first, to see if that fixes your problem. Sometimes dirty oil gets trapped in the switch and breaks down when the engine is warm. Replacing the oil pump is a major project requiring dropping the oil pan. Check U-Tube or a Haynes Repair Manual.

You may have some bearings down,,, on cam or crank,,, check with manual guage to make sure the electric ones are right first

check that you are putting the filter in the right way as you may be blocking the flow instead of filtering the flow.

I belive they didn't reset the oil light timer. I belive the sequence is 1. key on (not acc with engine off)
2. step on the brake pedal 5 times within 10 seconds. 3. key off. 4. start car. 5. check if the light went out. you may have to try it a few times to get it.
