leak on top of right cylinder head

[pab997]

I was changing my air fiter today and I noticed some type of fluid leak on the right side of the engine. There is a pipe that connects near the front (drive belt end) of the engine. It has wet fluid and dirt stuck to it where it connects to the engine. It is bolted to the top of the right hand cyinder head. It runs from the rear of the engine compartment up to this point. It is right near the air conditioner. I can't tell if it is an oil pipe or coolant. I think oil but not sure. I'm going to bring it into the dealer but I'm curious what it carries. Maybe it is part of the PVC system? Any ideas. I'll try to take a picture but it's pretty tight in there

Looks like the line to the oil separator to me.

I would have your dealer look at it and repair the problem. These cars should not leak any oil - period.

Does it look look this?

Went to dealer, they said they couldn't find a leak. It is oil separator line. They claim they tightend the clamp but when I looked at it, it looks like it is a slide on coupling. There is no clamp to be tightend. I cleaned the area and will continue watching for liquid.
