the most common places are : back pass. corner of the valve cover, oil filter adapter , and rear main seal. less common is the oil pan itself.

do you know on what part it is leaking from and are you sure it is engine oil or is it the tranny? what color is it? on and i checked on you jeep specs and i think you have the rear axle wrong they never made a Dana 30 for the rear but they did make a Dana 35.

My oil leak was from the oil seal located on the timing chain cover. I found that out when I changed my harmonic balancer. It was a quick fix and now little drops on the ground. :smiley-gen165:
