What damage does it do if the cambelt breaks?

If the cambelt (or timing belt) breaks, it can cause severe damage to the engine, particularly in interference engines where the pistons can collide with the valves. This can lead to bent valves, damaged pistons, and potentially a complete engine failure, resulting in costly repairs. Additionally, a broken cambelt will cause the engine to stop running, leaving the vehicle inoperable. Regular maintenance and timely replacement of the cambelt are essential to prevent such catastrophic failures.
