Hi all, new to this forum and my old 02 jeep liberty!
I’m just wondering if burning about a quart of oil every few weeks is normal? I’ve heard about jeeps burning a bit of oil. I live in the bush and drive a LOT! This old girl has needed a few things since I got her. Just hoping I don’t have to dump MORE money into her right now.

Welcome to the forums.
Should not be burning a quart every 3 weeks. Is there any oil leaks under jeep at all?
Do you see blue smoke out the tail pipe when revved hot?
Could be valve stem seals.
Probably best to do an engine compression test on all 6 cylinders as well.

I just checked and it leaks like a drop a day. No blue smoke or anything though. Ok thank you!

mine burns oil. usually happens during accelerations so you wont notice blue smoke at idle. You'll smell it though.

My 02 is doing the same thing, but there is definitely some white/blue smoke while it's warming up. No leaks underneath though. I'm pretty sure a crank seal is a "big" job for a casual DIY-er like myself, but correct me if I'm wrong. What about valve cover gaskets? Is that a reasonable weekend job for a guy with standard tools and a little know-how?

If you are blowing oil, start looking for a replacement vehicle. I wasted a LOT of money trying to save my 2003 3.7L after blowing a ring. Absolutely not worth it.
