Question about 1999 Dodge Durango

Oil pressure dropping to 0 after running for a few minutes

First of all let me say that this happened after we had a ice storm, I hit a large amount of water....as soon as i did the oil pressure dropped to 0. I was lucky to be very close to work so I left it in the parking lot and after i got off work it started fine...oil pressure seemed to be fine so i left it running to warm up but when i went back out the pressure dropped to 0 again. If you turn the truck off and then back on the pressure will be fine, but a few minutes later it will drop to 0....what could cause this problem? I'd like to have a few ideas before i have it towed to the mechanic.

    I had my oil changed in my 1996 dodge ram 1500 pickup at pep boys. Shortly after, the check engine light came on and oil pressure would drop after running for a few minutes. Occasionally it would come back up partially or raise all of the way up to normal and then drop back off again throughout my drive. I checked the oil and it had been overfilled. I never took it back to fix the problem. I have been driving the truck for two years with this problem with the check engine light on. Any ideas?

    is there any oil leaking from anywhere after you check to make sure the oil is full? The first thing that comes to mind are freeze plugs. Also check your oil filter. check the spark plug preasure also. Is there any milky looking substance on your dipstick? could be a cracked head. A splash of cold water could have cracked your head, or it could just be coinsidence. These are all the major things I would check first.

Locate your oil pressure sending sensor... generally near the oil filter intake but not always... give it a spray of WD40 to repel any water on it. next have the oil pressure tested just to be certain. the relay for the sending unit may need to be replaced as well... it's located likely in the fuse box in the engine compartment near the battery.

WHAT IS THE PROBLEM? I DONT KNOW WHAT TO DO.


Hello Tnelson, I had this happen to my Ford. There was debris in the crankcase. After driving ten minutes, the oil pump pick up tube screen would clog up and restrict the oil going to the oil pump. I drained the oil and poured a half gallon of liquid carburetor cleaner into the crankcase. I let the carburetor cleaner soak for a few hours. I drained the carburetor cleaner and changed oil filter. I installed the correct amount of oil and the low pressure problem was solved.

Oil pressure drops, metal shavings, and somehow my oil level incr


My truck does the same thing, pressure never drops to 0 but drops low, replaced the oil pressure sensor and same thing happened. My oil is always black and has a lot of metal in it, next time you change your oil, pour a quart of transmission fluid into the oil and let it run for 10 minutes or so, this should thin out the oil and possibly unclog some of the ports that may be gummed up. What could have happened with the dipstick is that the old oil was too nasty to drain all the way, with the fresh oil it could have thinned out and raised the level, try the transmission fluid trick and see what happens, next possibility is to have the engine scoped to see whats going on inside

Getting oil in radiator --but no water in the oil--its NOT a blown head gasket or head -we allready checked that out -it's a datsun 1971 1600 cc engine with very low miles =truck runs great


What about the possibility of a crack in head gasket between oil passages and coolant passages. Oil pressure would be higher than cooling system pressure, thus oil would be more likely to enter cooling system, than coolant enter oil /lube system. Just a thought. Have you done a cooling system pressure test, just to see if any drop at all in pressure? Seeing how engine would not be running, oil pressure would be 0, and may allow coolant to seep through same path, only from cooling system, to oil. Is it a large amount that your getting?

My oil pressure gage just drops to 0!!!


You need to replace the oil pressure sending unit, this is what tells your gauge what the pressure is. For future information if your oil pressure drops again and its a real failed oil pump within a few minutes you will internally damage the engine. I would get a new Oil Pressure Sending Unit. Let me know if you have any questions.... Thanks!

Car stalls when oil pressure drops...20 minutes to restart


No it is a fail safe. When your oil pressure drops below (on most cars) 30 psi your computer will shut your fuel pump down until you either let it sit for a while and it resets or until oil pressure builds again. Sorry!
