my car had a leak from a loose turbo inlet pipe (at least that's what the dealer told me...) the first week i had it. when it was a few days old, i noticed smoke coming out of the hood scoop, and that didn't strike me as normal. checked under the car, and sure enough, oil on the floor. i'd have it checked out pretty quickly.
Now I think I see. That looks like the line that carries the valve cover vapors into the intake. That is where people are putting the catchcan - inline on that line. Maybe the hose isn't seated properly and the oil vapors are gathering around it. Take a few more pictures if you could, but I think that's all it is. You do want this to be properly seated though.
