RE: DL-50 engine
yes if its cheap and flimsy,but this is the method used by many enginge repair shops ,you risk bending it if you use a piston stop,or even denting the piston ,or if you put hard plastic in the exhaust ,one could damage even more ,if the bolt dosent give,,a heat gun usually will allow the loctite to let go if it,(the bolt)dosent move easily
