Burns oil, badly
I picked up a 2003.5 liberty 3.7 limited about 2 years ago. It runs excellent and is a very comfy ride. Only issue with it is that it burns oil badly. If you don't check the level every 2-3 weeks, it will run out. I've already had to replace 1 cat that was ruined from the oil. But like I said, it runs awesome and still gets about 19 mpg.
I'd like to fix this, my guess is that the valve seals are the culprit. I can easily do the job myself.
Are the valve seals typically the problem?
