I just bought a 2001 TJ. It's my first Jeep & so far I love it!!
Anyway, I have read that they are notorious for Oil sending units being flakey.
Every once & a while my check guages light comes on & the oil; pressure reads low,,,around 20. It usually is 40 or above. I know the oil guages on the newer jeeps just like give an average rather than an actual continually changing reading.
My main question is can an oil pump intermittently loose pressure? Or do they work or not work?
I haven't heard any lifter noise or anything like that. And it seems to be running fine.
I don't know how to test the oil pressure. If Oreilly's can rent me a tool to test the pressure I will try that.
Any advice would be greatly appriciated.
