What Causes Abnormal Noise in the Timing Chain?

[SophiaAnn]

Reasons for abnormal noise in the timing chain: 1. The timing chain is stretched; 2. Abnormal timing sprocket; 3. Severe wear of the chain guide; 4. Lack of tension in the chain tensioner. Compared to timing belts, timing chains have better durability, save space, and are maintenance-free for life, which leads many people to overlook their maintenance. However, timing chains require regular oil changes, and the use of inferior oil should be avoided. The timing chain is one of the critical components ensuring the normal operation of a car's engine. With increased mileage, the timing chain will experience wear. Since the timing chain guide is made of plastic, it is also prone to wear over time.
