I have coolant coming from somewhere but it is not constant. I first noticed it from the dried coolant spots on the air box and surrounding areas from the fan blowing it around. That and where the metal is crimped over the plastic end-tank on the top there is dried residue. The problem is, is that I can't find where the leak is coming from. It seems to have started some where around the return hose from the coolant reservior for the turbo.

Has anyone else experience this? I searched and found that the plastic end tanks can leak. How I can I tell if it's the end tanks or the return hose?

I think leak is ony occuring under boost because I can only find little wet spots after driving it hard and not while it's running in the garage. It's not leaking a lot either because the coolant level hasn't gone down much.

I'm just trying to get some kind of definitive answer before I spend money on a new radiator.

From where I'm sitting I'd say it's a leaking end tank, but since I can't see your car from here, I think it's best to have someone take a look at it. A trusted mechanic would be your best starting place. An internet forum might not give you the best place to start a diagnosis.
