Hey all. First off...this is on a 97 Grand Cherokee. But since they motors are the same, Im sure someone in here can give me some help. Im also no stranger to working on stuff...so Ill probably figure it out. I just want to hear some opinions before I have to start to work on it...
I was driving my mom's ZJ this morning, and I noticed a weird noise. Sort of like an exhaust leak kind of sound. Jeep has a flowmaster, so I just figured it was a weird drone at first. Then I realised the oil pressure was at zero. As soon as I saw it was at zero I shut it off. Coasted alittle ways. Came to a side street and traffic was coming. So I had to stop. Then I had to fire the engine again, just long enough to bump it into gear and get me goin again, then immediatly shut it off.
If I had to guess...I would say I drove for about a mile for issues. Didnt notice the zero oil pressure at first. I went about 7/10s of a mile on zero pressure. Some of that was coasting with the engine off as well....
The jeep has plenty of oil. No holes in the block that I can see. And was running fine earlier when I left for work. My first thought was the oil pump blew. Then I got to thinking that a bearing spun. Even if a bearing didnt spin...Im wondering how much damage has been done to the engine. It has somewhere around 120,000 miles on it. Never a hiccup.
Any advice or help as to how I should proceed would be appreciated. Ive never had to track down an internal engine problem...but Ive torn them down plenty of times. So Im not scared of the work. I just dont want to waste my time doing something pointless. Thanks in advance for any help!!
