I have talked to three major Rotax Service Centers and they all say adding violet (strong) or blue (stronger) loctite to the engine mount cap screw certainly will not hurt anything. One even suggested using green (stronger yet) loctite if the bolts continue to move. All of them suggested not to use red (strongest) loctite in this application. Retorquing to a higher level helps for a longer peroid of time, but did not solve the problem of these bolts coming loose. Blue loctite was strongly recommended by experienced Rotax mechanics, and aircraft manufacturers I talked to.
