Unless the piston ring completely came off and is wiggling in the cylinder then maybe. Have you checked heat shields? Can't be starter, starters don't move unless your starting the car and if it was loose, you won't be able to start your car because it gets the ground like that. If its a really loud tick tick tick with the engine, then its a rod bearing. But I would check the easy stuff first, check all the heat shields and check for loose components before you go further.
