Also this is very important, Get a large regular screw driver, so when the engine does stick, you can stick that thru the flywheel hole and pry the engine unstuck. That way you won't have to remove the engine from the car. Remove the glow plug completely and pour a lot of after run oil into the engine, then heat it up and bump it a couple of times. Pour in some more after run oil put the plug back in it and don't tighten it all the way.
