    Arrow motor locked up

    starter will not turn crank shaft! Tried a breaker bar with spark plugs removed and serpertine belt off and motor locked up . Just heard one big bang when going to crank and it just clicks with key in ignition no movement. Will marvel mystery oil added to spark plug openings free it?

    How long has it been since the motor ran?

    Could free it up but the 'big bang' could mean the starter destroyed itself, flywheel damage maybe?? I've never heard of a rod going on startup but if something happened to the piston maybe but I'm really doubtful.
