Hi Andy
When I got the engine out, the bolt in the end of the idler shaft holding the cam pulleys had come undone don't understand why yet. Also a large lump of casting had come off the LH cylinder head, the mounting for the tensioner, and where the lifting eye is attached the engine removal.
The car is/was used daily, I live in Stockport and work in Crawley, gets two good runs a week (240 miles). Its now got 97K miles on it, bought it with 34K in September 2007. It gets regular oil changes etc. and is surprisingly quite reliable.
Changed the cam belts back in October after a cam belt idler bearing disintigrated. Done perhaps 5K since. I know for certain this bolt was not touched then.
