The remaining leak I have looks to be the o-ring on the oil filter adapter, hopefully not the rear main. The small spot is not centered under the Jeep, it is off to the right side. The starter and UCA on that side have oil on them. I can't see a rear main seal spraying oil on them, especially on top of the starter.

Don't know how much of a pain it is to change out the o-ring. When I can get to that I hope it is fairly simple.
