A Rod A rod is a unit of distance equal to 5.5 yards or 16.5 feet.
The rod is the part that connects between the crank and the piston. The usual meaning of throw a rod means it has broken off and is now sticking out through a hole in the engine block, which means you need a whole new engine. That's why you don't drive if the oil light comes on, or if you hear metallic knocking sounds.
