Has 200,000 miles. At idle the oil light comes on. Mechanic saiid oil pump is worn out. Can pump be replaced without taking engine out of car? Is it something a "shade tree" guy could do?
Yes you have to check your pressure with a mechanical gauge first. If the pressure reading is good replace the oil pressure sending unit. They are known to go bad, and oil pumps going bad is rare.
Oil pump went out on my 05 liberty. the sending unit hook up has a red tab you have to slide over to be able to get the squeeze tab to release.

I just encountered the same problem this morning. I will be looking into it. I have 164,000 miles. I will probably be hooking up a mechanical oil gauge if I can find the oil sensor. The crank and cam bearings may have excessive clearance causing the same low oil pressure problem.
I get the low oil light, but only at hot idle in the morning when idle drops below 600-700 rpm. 131,000 miles on the clock. I sure hope its not the oil pump. Let me know what you find out about the mechanical oil pressure gauge (ie where you hooked up, cold idle pressure, hot idle, etc.)
Thanks.
I have the same problem. I found the sending unit, it is above the filter. With the filter off I can reach the unit but can not see it to find out how the clip works. Any ideas? I can not pull the connector off.
I havwe the Same Jeep liberty 2003 V6- 70000miles, oil lamp is on at idle only
