What happens if my timing chain fails?
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.
Can you drive a car with a stretched timing chain?
It’s probably not immediately “dangerous” to drive with an elongated chain, but if it gets elongated enough, it will lose tension, start to “slap”, and may break the plastic cam chain guides or jump a tooth on one of the sprockets, which may cause catastrophic engine damage.
