Will the timing belt breakage on the Besturn B50 cause valve damage?

[StBarrett]

If the timing belt breaks, it generally causes valve damage. Engine shutdown: When the timing belt breaks while the engine is running, the valves and ignition system will fail to operate properly. The pistons continue to move up and down due to inertia, while the opening and closing of the valves stop. In the confined space of the combustion chamber, the pistons are highly likely to collide with the valves. In such cases, the engine will either require a major overhaul or be completely scrapped. Manufacturer requirements: To prevent timing belt breakage, manufacturers have strict requirements that the timing belt and its accessories should be replaced within specified intervals. According to the engine maintenance manual, the timing belt should typically be replaced when the vehicle has traveled between 60,000 to 100,000 kilometers.
