So new to the site, and have a couple of things to sure and ask. Well first I did a trade for a 99 Cherokee, and the motor was blown and when I checked it had Apple juice in the oil pan, and oil in the transmission, so thinking that I need to clean the gas tank and lines. Any ideas? And now am going to remove my motor out of my 91 Cherokee and trans and thinking of pulling ever thing out of the 91 and putting it in the 99. Hmmmmm, any options.
