I have a questions for those that know about motors, I have a '92 YJ Islander that I just bought. It has 161,000 miles w/ 6 cyl. 4.0. It has 31" tires. The jeep's engine is showing it's age. Times are tough so I'd like to give this Jeep new life, but what is the best way to do this on a tight budget, Remanufactured motor, rebuild the one I got, or getting new engine all together. I don't know a thing about this, but I don't want to get ripped off due to my ignorance. Can anybody tell me what they might do in my predicament.
