What happens if the timing belt skips a gear?

When the timing belt skips a gear, it disrupts the precise timing required for the engine's valves and pistons to operate in sync. This can lead to severe engine malfunction because the pistons may contact the valves, causing significant mechanical failure. In most cases, if the timing belt has skipped a gear, the engine will indeed be unable to function properly, leading to a situation where it won't work at all.

Proper function relies on the timing belt maintaining the correct timing between the crankshaft and camshaft. If this timing is lost, it not only affects engine performance but can also lead to catastrophic engine damage, which is why the condition of the timing belt is crucial in vehicle maintenance.
