More oil pressure problems
"red "Check gauges" light was lit up. The oil pressure gauge was at 0"
1997 Jeep is new to me with 130,000 miles. Runs great except for the oil pressure dropping to 0 at idle after warm-up to operating temp. Dip stick shows the engine has oil to the "safe" mark. Replaced the oil pressure unit (with factory unit) but the problems continues. I did the instrument test and all gauges and lights work correctly.
Someone suggested changing the oil to 30 weight given the high mileage but that didn't stop the problem. Another suggested dropping the oil pan and cleaning the screen. Have not done that yet. Any other ideas/suggestions would be appreciated.

|Jaxon1023||Mine does the samething. I need to change the sending unit but I check and change my oil religiously so I know the gauge is full of it when it does it lol.|

|jickey||Mine was doing the exact same thing. I changed the sending unit and it's worked fine ever since. Not expensive at all - oil, filter, and sending unit together was exactly 100 bucks at Auto Zone.|

|kfdjason7620||I would look into a new sending unit. Its right beside the oil filter on my 2000 4.0. I picked one up from Napa about 4 years ago and its need fine ever since. If I remember correctly, it was less than $30|

|kfdjason7620||Hold the odometer reset and turn the key to the on position. All of the gauges and lights will go through a self check. You will be able to check to see if the oil pressure needle is sticking|

|kfdjason7620||The oil pressure sending unit could be going bad. Mine did the exact opposite. It pegged high at idle and actually dropped down when the rpms increased|

Oil pressure issue
Driving home after work today I came to a complete stop at a red light and I heard a loud "beep". I looked down at the gauges and saw the red "Check gauges" light was lit up. The oil pressure gauge was at 0, I didn't hear any knocking or taping sounds. Light turns green and I let out the clutch and start moving, as the RPM's increased so did the OP. Now I'm crusing at 35-40mph and the OP gauge is at around 40. Come to another stop and again the sound goes off, "check gauges" lights up and OP is at 0. Since Im pretty close I decide to limp it home but again the OP gauge goes back up to 40. Just checked the oil dipstick and it's kind of low but not where I would think that it'd cause the gauge to bounce around as much.
No other gauges seem abnormal, no knocking or ticking sounds so what could it be?
