GMC appear to be making good progress.

I think I'm going to treck oop North on Friday this week to do some extra prep work on the engine bay, now the lump is out

Turbo has been sent away for diagnosis - should find out what the problem was in the next day or two. Lets hope its not something too expensive
The jobs list has now been agreed, but I dare say a few extras will creep in during the build (isn't it always the case?) The only thing that is certain, is that I'm not going to like the bill one bit!
