I appear to have a leak, of some sooty stuff, from the curved metal pipe in the photo, where it joins the manifold.
Is this pipe part of the EGR system?
Sorry for poor quality picture - I had to use my webcam cos' my card reader has bust!

Ideally all that pipework, diaphragm and control stuff could come out if you could permanently seal the entries for the inlet and outlet manifolds. It would make for working on the engine a lot easier. It's just having the inclination to get stuck in .....I took the "technical" route as a temporary measure.
