I think its from the HG

 

Got a 2nd shot from a wider angle so we can tell what we're looking at? Is that the hard pipe that runs above the exhaust manifold?

While I'm sure anything is possible I don't think I've ever seen a HG leak externally. My guess is that it's something else.

 

It's right below the last Allen head bolt on the cam housing . I can't see where coolant would be coming from in that area other than the gasket, everything else is dry. I will see if I can get a better picture later.

 

there is the coolant neck on the back of the head, drivers side. maybe it is running down it to the headgasket and coming around the back side of the head to the exhaust area.

 

Here's a better picture, but its difinitely coming from the head gasket, I clean it off and with a mirror was able to see it start to leak out slowly. I just had the cam housing off last week to replace the gasket.

 

Odd – that’s a picture of the oil return galley area.

 

Any ideas Chris? I cant see it coming from anywhere else, as much as i try! I was hoping to get the car to the dyno with the new turbo and M-tune installed.
