What happens when you over tighten an oil drain plug? When you over tighten the plug, you are damaging the screw pitch. In the case where the plug is over tightened, you have to change the whole oil pan. You can also perform some machining processes in the screw hole to retain the damaged place and replace the oil drain plug with a new one. Can a car drain plug be removed to change oil?
