I really don't know if it could be a slipped timing belt. I'm pretty much flailing about in the dark, I think the only option is to work my way through in a vaguely systematic order and try and eliminate all possibilities. I don't suppose someone would like to package up Russell and post him out here?
I have to say, I was pretty chuffed that the Clubman and the Jag were not getting away
I pulled the rocker cover off this evening and cranked her over, there doesn't seem to be anything spectacularly obvious there, but in the interests of keeping everyone informed and involved here is a video.
