What are the precursors of timing chain failure in the Regal?

[JonathanRose]

Precursors of timing chain failure in the Regal are as follows: If the timing chain fails, there are usually precursors, such as the engine making abnormal noises. In addition, timing chain failure can also lead to increased car fuel consumption, difficulty in starting the car, weak acceleration, sluggish response, and severe exhaust emissions. Extension: The timing chain is lubricated by engine oil. 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, and it may gradually stretch. Stretching can lead to tooth skipping, causing engine failure.
