Ok went and looked at my first Cherokee on my search wasnt a bad little unit. Ran great all blinkers and electrical worked. One door wouldnt open and no rust. Biggest thing that was concerning to me was on the passenger side of the motor it was covered in oil. Im guessing this is from the valve cover gasket. Is this correct and how hard is this to fix? Also where are the problem spots besides the filter stem and what should I be expecting when I'm looking to be in the 2500-3000 dollar range.
