Message It appears I've got a leak from my passenger side turbo line. What's weird is it seems confined to leaking around the fitting on the turbo (little wetness can be seen) but then running UP(?) the line and conforming to it as it curves around the turbo to the connection below it. There doesn't seem to be oil anywhere else, just on the line and a little on top of the turbo itself. I find it strange that there isn't oil on the back of the turbo or on the down pipes, just on the line and around where it enters the turbo.

Here's a pic:

And here's a short video clip showing the line and a little above the line where you can see the oily coolant line bracket if you pause it near the end about the 46 second mark:

I guess I'm looking for confirmation that you guys think the leak is coming from where I think it is, and then also suggestions on how I might fix it. Does the whole line need to be replaced? There doesn't appear to be any o-ring associated with that end of the line according to the part fiche in the Docs section, so it doesn't seem a part like that has worn out.

Can it be tightened or once it is leaking the fitting is toast and the line has to be replaced?

Any help or tips for repairing (with engine in car) appreciated. Thanks.
