What are the consequences of a timing belt breaking while driving?

[VonAlex]

If the timing belt breaks while driving, it can cause the engine's valves to collide with the pistons, necessitating a major engine overhaul. Generally, if the timing belt is properly maintained and replaced according to the manufacturer's recommended mileage or time intervals, it should not break. Here is some relevant information about timing belts: The timing belt is a crucial component of the engine's valve timing system. It connects to the crankshaft and ensures accurate intake and exhaust timing through a specific gear ratio. Belts are used instead of gears for this purpose because they produce less noise, have minimal variation, and are easier to compensate for. However, it is evident that belts have a shorter lifespan compared to metal gears, so they must be replaced periodically.
