Hi all,
I need help trouble shooting a major oil leak leaking from somewhere up top, but behind the engine is all i can see. I have a 2015 JK 2 door 3.6L

I removed 6qt and replaced with 6qt of Pennzoil 5w 20w oil filter MO-349 all purchased from WM. the filter shows no signs of leaking.

 

That sounds like an leask from the oil cooler assembly which is on top of the engine and under the intake. Very common issue on the 3.6L '14+. Usually the oil will pool in the valley and then exit out and down the back of the engine.

 

dang, thats seems exactly what its doing thanks! ill look into it further in the day light tomorrow

 

A lot of times it seems it's just the o-rings on that and they sell a kit for it. I believe the Mopar cooler is on national backorder. Someone recently used a Dorman I think and said fitment was fine. Obviously it's a decent bit of work to yank the whole upper and lower intake off. If you are anywhere close to replacing spark plugs that is the time to do it.
