What are the symptoms of a timing chain failure?

[StElijah]

Symptoms of timing chain failure: engine noise, car unable to start, insufficient power, severe exhaust emissions, etc. Causes of timing chain failure: 1. The timing chain comes into contact with oil or other solvents; 2. Failure to promptly inspect and adjust the timing chain tension, resulting in skipped teeth. The timing chain relies on lubricating oil for lubrication. If the engine oil is not changed for a long time or the oil quality is poor, it can easily increase the friction between the timing chain and the sprocket, reducing the lifespan of the timing chain. If the wear is severe, the timing chain is prone to failure or damage, gradually becoming elongated, which can lead to skipped teeth and cause engine failure.
