What happens if a timing chain breaks?
A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.
