Well it runs on the 60 at about 2100rmps in fourth, it's normal at a idle. I haven't been too concerned about it in my 95 Dakota it always ran a little high also. Main thing I was concerned about was oil on the air filter. I wasn't sure if it was common or not. This is my first jeep. I've owned it a little over a year now and have done some maint on it(distributor, crankshaft sensor some simple fixes like that. )
Mine is the same fresh overhaul. Not an issue. The only bad oil pressure is zero.
My psi at cold temps is 70 at 2000rpms
Warms up and stays around 50 ish
Idle around 40
My old xj ran 18 on a hot day
My older xj ran 12 but I'm betting it was sludged up and I didn't take the greatest care of it. At 198k it developed a bad o ring gas leak and was sent to junkyard heaven...
I bet it is your sending unit about to go out. I had a similar problem until it was reading extremely high. Then I developed a leak that got progressively worse. When I finally dug in I discovered the sending unit was bad and oil was leaking through it.
I replace the sending unit and my pressure went back to normal and the leak was fixed.
If it gets higher and starts leaking you might look at sending unit.
It might be my sending unit It looks like I might have a small leak. I can't tell from where I had a bad oil cap a few months ago and it's been to cold to clean it off( I work 5pm to 5am) would the leak be on the drivers side of the engine? I don't have any drops or leaks under my jeep when I park it just some on the side of the block( I can't tell if its new or not though.
Mine sat all the way up as high as it reads until one day I looked at it and my stomach dropped noticing that it was on zero. I immediately check that I had oil and turns out the sensor was bad. $38 later its good as new, sitting just as high as your currently.
Yes. I believe its near the oil filter. I haven't changed the one on the 2.5 but I did on the 4.0 3x
I used a crescent wrench.
Screw it back in. Tighten but not super tight
Plug in connector
