Its a pretty easy to do. I was a little apprehensive before dropping my pan, but once you get started and pull it off its not that hard. You also might want think about changing the valve cover gasket aswell. Found a little leak from the rear of the cover. My WJ has around 160,000 miles and it was definitely time to change those gaskets. Now, no oil leaks anywhere. As far was removing exhaust pipe at the manifold, starter and engine mount, I didn't have to do any of that. Although, I noticed how much easier it would have been to remove those, but its do able without have to remove those items. Just need a little patients.
