Am not entirely sure... I believe it is completely cream crackered, a conrod has let go and caused so much internal damage that the starter motor needs replacing, as does the clutch which is contaminated with oil. Not heard from Bolton since last week as Dealer Principal has been away. Their view seems to be that it's nothing to do with what they did to it last year but I'm not yet sure how they can reach that conclusion given that we don't know (and may never know) what caused it to let go? It is apparently more cost effective to fit a new engine than strip down mine. I am, obviously, at this stage, over the fucking moon!
