I have done a search for this and not come up with anything sensible. I am sure there was a recommended or maybe even obligatory modification for the fixing bolts for the camshaft timing wheels. My 2012 M3W is currently at RD Racing near the Paul Ricard circuit in France, for a large amount of work, chassis reinforcement, change to lightweight steel rear sprocket, change to high temp oil lines plus a major service etc etc. The engine is out anyway for a new style Centa Compensator to be fitted, so the camshaft timing wheel work could be done at the same time. I should be very grateful if someone could bring me up to speed on this, so I can advise the dealer.
We have been without a service dealer in the area for two years now, so there was a lot of work stored up for the new people to do and I would like to get it all done at one go. This will be the first M3W he will have dealt with officially, as the Morgan service dealer, apart from a friend of his, whose M3W he has known for some time. However they seem extremely competent.
It is a nightmare to get back to my house from Paul Ricard Circuit/Signes, as there is zero public transport. It was three taxis and two trains to go a total distance of less than 70km as the crow flies but not as taxis and trains go, taking over three hours. I don't know what they will do when the French GP is there next year as the roads are poor and public transport worse.
