2007 4 Door Wrangler Unlimited X Oil Leak

Just bought a 2007 JK and when I checked the oil at purchase it was about a quart and a half low. Didn't think much of it at the time.

Two days later I noticed there was oil stains on the pan and near the pan. Since adding the oil 3 days ago, I haven't noticed any spots in my garage. But, after looking at it this morning, I think I see fresh oil on it. It has leaked, but just enough when I run my finger across it to pick some up.

Questions:
1. Is a leak this minor something to worry about?
2. I've read many posts about oil leaks in this model, and hear it could be oil pan gasket. Based on the below picture, is this a possiblity.
3. I've read posts where there were TSB's for the timing case having issues. If this were the case, would I see oil at the top of the engine near the timing case? Or is this leak concealed from view.

That wet spot running down to the LEFT of the drain plug ????
You might check the pan bolts, but don't over tighten them.
Not sure about the oil pan gaskets on these MOPAR engines... Some have a rubber seal around the front and rear of the pan, not sure if MOPAR is like that...
If it continues, you could change the pan seal, that should be pretty easy on the Jeep, it's easy to get at.
Maybe if you dry it off real good and squirt some cleaner in there , wipe it down and watch it real close you will find out for sure where it's coming from.... Looks like there is a separate casting between the oil pan and block. Could be it's leaking between the two parts...
I have a 07 JKU-X, It uses oil but I cannot find any leaks anywhere, does not drip at all..
Interesting, maybe I'll get under mine tomorrow and see what it looks like...
Good luck ! "BH"

Baby Huey - did you ever get under yours?

I've decided to just clean mine real good and try to see exactly where it's coming form.

Two weeks and still no visible spots in the garage. So maybe not a huge deal.

Nope, Not yet..... I put another 80 highway miles on it today. I'll try to get it up on the stands Sunday and inspect it a little closer ... Need to do a little grease anyway...
I got my pressure washer back today so maybe I'll give it a bath.

You know what you said about yours being LOW on oil when you bought it. Makes me think that if they changed oil they may have just dumped in 5 qrts and screwed on a filter and done deal....
They require 6 quarts.....6.1 or something I think...

Good luck.... "BH"

Possibly a valve cover leak also. They occasionally drip at the back and down the motor and trans. Could also be an oil pan, more likely.

Could be rear main as well. Leaks are never good, but manageable if you frequently check your oil. I am fussy and like to fix all leaks. Clean the underside well. Check it after a short ride to locate the leak.
