well I can tell you now that what your doing will never work. Why? Because loctites arch enemy is heat. If you need to release a loctited joint then you heat it! Steam cylinders get hot and stay hot. They also are subject to a lot of oil. This also degrades loctite.

Save yourself a lot of aggro and put the glue away. It will not work in this application. Will's (Made in England) suggestion is the best so far as it is more or less what we do in the larger passenger hauling scales (though we don't use the threadlock with superheated steam for exactly the reason stated above!)

Or better still just save yourself all the hassle and get the piston upgrade kit from dream steam. At £12.99 it will fix the problem permanantly and give you better performance to boot.
