3.6L Oil Leak
Looking for some advice on an oil leak I’ve found. 6 months ago went on some trails and found oil leaking pretty good. It came from the top of the bell housing so I went ahead and changed the oil filter housing. Now I’m still getting a little oil around the bell housing/driver side of the engine. It seems to be coming from right above the AC compressor and making its way back. When I did the oil filter housing I had to replace the lower intake manifold due to a stripped hole. I don’t think that would be the cause of it though. Any ideas? Can’t seem to find anyone else with the same problem.

Common leak???
Had another look at mine this morning and appears to be around the head gasket area as can see the metal gasket...🤦🏻♂️
Going to clean the area and keep a close eye on it.

I’m not sure. I was never able to find anyone else with a similar problem. I cleaned the area really well with brake cleaner. After a few months or so it didn’t seem to come back. Maybe a little weeping but not much. To me doesn’t seem to be that big a deal. I’m pretty sure I did read a recall about the 3.6 in the Caravans cracking on the left head so maybe it’s the same problem but more rare.

I don't seem to see many 3.6L JKs with head or valve cover issues, though that doesn't mean that can't be your issue. However, these dang oil coolers are such a common problem that it would be the most obvious thing/area for me to inspect around real good to rule out first. Most of the time that oil is dripping down the back though which is obviously a bit different than what you got going on. Is the back side of the engine bone dry?

Mine was like my pics when I brought it a year ago and thought someone before me had just spilt some oil when doing a service. I de greased the area and the leak appeared to be gone until i checked underneath after washing the Jeep the other day. So I suppose not a bad leak after a year/ 20 000ks driving....

That's what I thought too as never really heard of it being an issue but I'm still pretty new to the Jeep world!
I'm 99% sure my coolers ok as check it every service and there's no oil down the back of my engine, it's definitely bone dry. I'll just clean it off and keep a close eye on it 👍🏼
