Its not the oil relief valve,since it only works when pressure is to high,and even then you dont lose all pressure.. look into the camshaft synchronizer having a broken drive gear at the bottom.they tend to break..working on one now that has this problem,so I know. luck to ya!

Most likely your oil pressure relief valve located on in or nearby pump. Symptoms are oil pressure will drop when warmed up when idle lose all pressure eraticly giving the vehicle gas will bring back pressure and highway driving will bring pressure up until idle again.

Is the oil pump in the oil pan on a 2003 Ford explorer 4wd 4.0
The Ford Explorer is know to have Oil Pressure issues. Try replacing the oil pressure sensor first as these sometimes clog up. It's also a much cheaper fix saving you a lot of time, money and unnecessary work if that was the actual problem. The pump should be in the oil pan directly connected to the oil pick up pipe at the Flywheel end of the engine.

Knocking in engine and low oil pressure usually means bad main bearings. May have been caused by bad oil pump or just worn out bearings due to high mileage. If this is problem needs engine or rebuild old engine.

302 ci. 5.0 ltr . oil pump replacement
Why do you want to replace the oil pump? I am asking this question for good reason. Engines that have worn bearings will have low oil pressure, and replacing the pump will not solve this problem. If you are replacing the pump because of low pressure, then you really need to consider correcting the cause of the low pressure. To replace the pump, you need to remove the oil pan from the bottom of the engine, which will likely involve raising the engine. Once the oil pan is off, you can readily remove and replace the oil pump.

I have a 97 Ford Ranger with a 4.0 with 122,00
Check your oil pressure gauge sender first. It might be the pump but often they wear down gradually. It might also be the pressure relief valve spring. Most likely it is the oil pick-up pipe in the sump. Take the pan off and inspect for crud blocking it. If clear it will be very easy to check the pump. The pump vanes are driven directly so any free rotation would indicate a (rare) pump failure.
