Where is this oil leaking from?

I noticed some oil dripping on the driveway and have smelled burning oil when at the lights. I removed the skid plate and noticed the oil is dripping somewhere right and back of the engine. It seems that it also drips on the catalyst so that explains the smell. Anybody have any ideea where it might come from?

Check your CCV hose.It's on the rear of the valve cover on the passenger side.Maybe it came un-hooked.

It's not the ccv hose. I took the cover off and cannot see any oil, not around ccv nor anywhere.

Is it motor oil or trans oil. The trans cooler lines usually cause problems like this..

Have them check the sensor in the trans pan. I believe it is at the front of the trans just about the pan. They say the o-ring for the sensor goes bad and it drips right onto the cat. Burning oil smell..No good!

Trans oil is usually a redish tint.

Trans oil is usually a redish tint.
Not if the person has never changed it and is agressive on the tranny. Then the trans oil can look like fresh oil. But if he's saying the oil is dark... then thats a different story. And, he needs to get the oil changed too, lol.

I have the same thing happening on my Jeep. At first I thought it was the dpf regenerating but then I noticed where oil has been dripping down and burning off of the catalyst at the right rear of the motor. I suspect it is coming from the PCV valve which is right above but I still have warranty so I am going to the dealer and point it out to them.
