Oil leak

Okay, so I bought a WJ a few weeks back. It is leaking oil somewhere, but I cannot seem to find the source. 150k on the engine, so I am certain nothing has been changed. I am going to be gone for military obligations for about two months, so I thought about leaving it with my cousin to repair and replace some stuff. Any thoughts/ideas on what all I should replace?
BTW, the leak appears t be worst at the rear of the engine, in the proximity of the oil filter.

pics would definitely help.... but rear main, the oil filter housing itself could be leaking, the valve cover could be leaking in the back and running down, could also be the oil pan gasket.

Best thing to do is power wash the underside really well, maybe use some degreaser, and then you will have a better chance at pinpointing where the leak is coming from.

Thanks Aaron. I will try that. I can try and take a couple of pics too. Looks to have a leak around the fitting that goes into the power steering pump also.

My Jeep also went through quite a bit of oil between changes. About 1.5 quarts every 2k miles. All of the following contributed to my problem: Valve cover gaskets, valve seals, and breather tubes on back of engine (connected to a vacuum on the right side of the resonator box). These can cause quite a bit. I changed them all myself and now it burns significantly less. Hope this helps.

My '99 was showing oil in the same place. In addition to what has already been mentioned, check your head gasket on the right side of the block. That's where my leak is. Remember, in a moving vehicle, fluids travel to the rear and downward. Inertia and gravity.
