I have a 98 XJ Limited 2wd with the AW4 and I've read most of the older posts on faulty oil pressure sending units. My question is to help me avoid throwing new parts at a problem when I'm unable to diagnose my way to a solution without spending money. The oil pressure gauge in my Jeep runs on the low side (like a lot of them from what I read) I have 144k on my XJ and I belive the sending unit might be failing. I have zero knocks or noises from the engine bay and the Jeep is a daily driver. I just get nervous when it shows 10-13psi at warm idle. I get about 35-40 at cold idle. I tried to take everyone's advice and rent a mechanical pressure gauge from my local parts place to verify the sending unit is heading south. When I asked the parts person if they rented these gauges he asked me what the gauge was for....and no, they don't rent them. So my question is......should I spend $20-40 on a mechanical gauge to test my condition or just bite the bullet and order a new sending unit from Jeep for $52. I'm not about to throw parts at it, but I'm fairly confident this is the issue and I don't want to spend money on a mechanical gauge only to have to spend more money on the sending unit. Any thoughts? Thank you in advance.
