When I picked up my car at the dealer after the Centa drive installation he told me he had put Loctite on the camshaft pulley bolt.
This to prevent that the bolt would come loose.
Not sure if he also installed the new kit but I don't think so.
Now I'm in doubt if only this Loctite will do the job.
Peter Dron, who suffered the issue in his car BTW, mentioned in his M3W book that S & S advised against the use of Loctite on this bolt - no idea why.
Indeed, it remains a mystery to me and that failure was expensive and frustrating. The repairs were of course carried out under warranty, but that does not cover a train fare and hotel bill when your dealer is a few hundred miles away.
While writing the book, I had trouble getting info from S&S and it was only through the helpful intervention of my good friend Pete Larsen that I was put in touch with a man who was prepared to collaborate. This was rather late in the day and I was up against a deadline. He helped as much as he could but I felt that, er, there was some confusion within S&S...or an unwillingness to discuss the problem.
Some time afterwards, the man who tried to help me left the company.
It seems obvious to me that 1) the original bolt was wrongly threaded and likely to become loose, especially considering all the vibrations within the engine; and 2) some kind of adhesive of the blue Loctite type was essential.
I am not an engineer but sometimes you do not need to be to spot the bleeding obvious!
