For those of you who have used the antifreeze in the crock pot method for cleaning your engines, do you need to dissasemble the engine into pieces? I know you have to remove the carb because of the o-ring and seals, but what about the rest of the engine, ie bearings, rings, etc. If you cover the holes (carb/glow plug) will the antifreeze damage any of the engine internals if it seeps in? Thanks, DG
