nope bought it new

it's a 2005, not sure if that makes a difference. I found a video of a guy doing a valve cover gasket change and after he pulls the top cover (not the valve cover, but the thing that says "16V blah blah" on it) you can see the nipple sticking out with nothing attached to it.

Look 1:04 in.
