Thanks Gerald, I am going to clean the area this weekend then keep an
eye on it. Going by how the leak appears to be pretty high up I would
think valve cover or main seal... mileage is 76,000 and change so I
guess its time.... pretty much all are beyond this back yard mechanics
realm of doing myself so I guess a call to my mechanic will be in
order... :(

The valve cover gasket is an easy fix. Sometimes all you have to do is
tighten the loose bolts. Go feel them with your fingers, bet some are
loose.

Does anybody offhand know what size tool to use to remove the oil filter
adapter. I need to replace my O-rings. 93XJ. Any help is appreciated.

Re: Common oil leak on a '98 XJ 4.0?
 

Well could be one of 3 different tools, either a 5/8's (?) wrench, a t50 (?)
torks bit (thats is one of those 6 pointed stars) or a metric Allan wrench,
I eventually ended up having a local shop change my seal's when they changed
my valve cover gasket and changed the rear sway bar and front track bar,
wasn't to bad of a bill either as I supplied all the parts I only had to pay
for labour and taxes. Now I just need to replace the track bar frame mount
due its heavily worn.
