Oil pressure issue

When I start my 2000 XJ the oil pressure gauge reads 60 at idle then under load goes up to 80. Going to try a new pressure sending unit to see if that solves the problem. I donít have a gauge to see if the gauge is correct. The Jeep has the proper amount of oil in it. Is it ok to drive it. Iím going to need to drive it to pick up the new part. Does anyone know what size socket I need?

Re: Oil pressure issue

Short answer is that it should be fine. Upon first start up, the pressure will be higher until it warms up.

Have you recently changed the oil/filter?

You don't say what brand and viscosity oil you are running.

Worst case I might change the oil filter, especially if you are running FRAM.

Re: Oil pressure issue

Of the 3 Cherokees I've owned (1984, 2001, 2001) 2 of them have had oil pressure senders fail such that they read way too high. They would read idle pressure normal but revving the engine when hot would indicate 80 psi which is virtually impossible.

If your oil viscosity is correct this is your likely problem.
