Does a fire truck suck up water when there is a flood?

Overbored. A cylinder (in which rides the piston) is a certain diameter when the engine is new. As it wears, the cylinder wall gets scratched or worn, until it's no longer round-enough, or sealing properly with the piston rings, or holding the piston straight enough. Then you pull the engine apart and bore the cylinder a little bigger, and put in a bigger piston. That cylinder is now overbored.
