Its fate the van doesn't want to leave you! I know Peter Fletcher i have been using him sporadically for over 15 years! He will sort it for you no doubt. Is Ermintrudes van back there again, new engine must be ready to be installed?
It was in his "compound" and there was a nice shiny engine in his workshop so presumably just waiting to go in....
Right, as you were, Peter has put the new head on, bus is cantering along nicely, price is as before £12,000 Ono
