Could be just the sending unit for the gauge or warning light.
If it really did loose oil pressure it could be the oil pump or the screen in the pan.

SOURCE: Losing Oil Pressure in Dodge Ram

I have a 1999 dodge ram with a 5.9liter. Come to a stop and bam no pressure. Replaced sending unit twice. First after market, then mopar. Problem is still there. Replaced pump. Problem was still there. So I talked to tons of dodge mechanics, and this is the real problem. Who ever said that these engines are none for sludge is just reall really stupid. BOTTOM LINE ON THAT FACT. Sludge comes from neglect...
Dodges oil pump makes 8-10 Psi at idle. Always mechanically test that no MATTER what. But the sending unit needs 12-14 psi to read it. So what happens is the engine warms up, and the oil thins. Then you come to a stop, and rpms are low, and your not producing enough psi for the sending unit to read it. So your truck is fine. But if the chime is getting to you. Install a high volume pump. I returned the stock one, and got the high volume pump. I will bet if you change your oil every 3,000 miles you will not see sludge at all. If your dodge has high miles replace valve cover gaskets, becauce the high volume pump may cause the gaskets to leak. Whoever said ther none for sludge just has no love for a dodge, or is a moron mechanic that is stuck in his ways. High volume pump is the fix $85.00 plus pan gasket. If you have a 4x4 you can do it yourself. Drop the starter. Remove torque converter cover. With a 13mm socket with a variety of extentions, and removing a dozen bolts. Do it yourselfer will complete it in 4 hours....

SOURCE: amount of R134A refrigerant and compressor oil to use in system?

Sticker should be right on top of compressor...Don't use anything with sealer in it. I don't recommend doing anything else but perhaps a squirt into a known good slightly low system without complete equipment and training or it can cost more in the end than having it done for you.

SOURCE: 1996 DODGE RAM 1500 LOSES OIL PRESSURE AFTER

There are several reasons. The oil viscosity can make a difference and if the oil is contaminated with fuel. Wear in the oil pump and all of your bearings starting with the main crankshaft bearings and the connecting rod bearings. The wrong or bad oil filter.
When cold oil flows it plugs leaking bearings and oil gears. When the oil warms, the wear in the bearings (gaps) can't hold back the thin oil and the pressure drops. If the bearings are replaced before the crank and cam are damaged, the pressure will be maintained.

My 1998 dodge ram 4x4 is dropping oil pressure, I replaced the oil pump but it is still dropping to 30. any suggestions?


I'm assuming that pressure is at an engine speed of 1500 RPM or more. You could have excessive clearance in the main, rod and/or cam bearings. No easy way to check.

I have a 1998 dodge ram 1500 v8 and theres a knocking on the right side of the engine and it sounds like its going to throw a rod bearing but not sure and it also has no oil pressure


Sorry. From the sound of it your motor is done for. A knocking sound and a loss of oil pressure are the last two things you ever want to have in a motor. If you have any plans of reusing the block for a rebuild I strongly suggest not running the truck anymore. If it does go to pieces the price tag will go up greatly. But, if I had to guess I would put my money on the main bearings. Simply because of the oil pressure issue. Sorry. Good Luck.

Loss of oil pressure


Loss of oil pressure can be any of the following: defective oil gauge, defective oil gauge sending unit, defective oil pump, worn rod and main bearings, plugged oil pickup screen, insufficient oil in engine hole in oil pickup tube, etc. Many issues can cause low oil pressure. Take it to a mechanic for proper diagnosis.

Oil pressure fluctuating


The sensor could be failing to read the lower pressure when the engine RPM slows down. Or the pump could be failing. I would replace the sensor and see if that doesn't correct the problem
