A few weeks ago noticed a few drops of oil on my garage floor. Went under the Jeep and noticed wet motor mount on the driver side. There was a small oil droplet that was about the fall down, wiped it clean thinking maybe it had to do with a recent oil change. Inspected upper engine area and discovered no overfilling or messy oil change issue. Today it appears that the oil leak is originating from driver side valve cover, Although not a 100% diagnosis as Jeep's engine area is so packed, you can't see anything.
I am hopping to get some response from fellow Jeepers to see if other have had this issue. There's one post that I could find in this forum by #
JudgeTread that had similar issues. Attaching some photos for reference.

Any input would be greatly appreciated.

Not much else to leak on that side. 3.6, I assume. Either valve cover gasket or something stuck to/through the valve cover most likely.

Upon further investigation I discovered that the most probable cause is from spark plug tube seals.
some youtube reference -
Interested to hear what anyone thinks.

Did you look at your own vehicle or google things until you chose a problem you like the sound of?

I removed the plastic engine cover and looked at the passenger side and BINGO, Passenger side spark plug surroundings are very wet. Which leads me to believe drive side is going to be worse. Unfortunately driver side can not be examined without taking the intake apart (which is a big deal for me, since I want the dealer to do it under warranty). So far all facts point to spark plug tube seals. I have an appointment with the dealer tomorrow, Let's see what happens.
