Just bought an 04 KJ 3.7 5 speed 4wd for $700.00. Has no compression on cylinder 5. Found a used engine local for $850.00 with 141,000 which oddly enough is the same mileage as the Jeep. I fixed all the rust on my 96 XJ a year ago and gave it to my brother. I missed my old faithful XJ. We need a Jeep for our vacation house in MT. I’m hoping this will be a nice little rig once I get done with it. My plan is to get this thing running and drive it out west for Xmas. I’m looking forward to getting to know some folks. I’m hoping this forum will be as helpful as the XJ site.
