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.
