What are the effects of engine chain noise?

[StAliyah]

Engine chain noise can affect power. The causes of engine chain noise generally include: insufficient tension in the chain tensioner, elongation of the timing chain, abnormal wear of the guide chain plate, and abnormalities in the timing sprocket. Below is relevant information about engine chains: 1. To prevent excessive clearance due to chain wear, the system is equipped with a chain tensioner to automatically tighten the chain. This tensioner operates based on oil pressure. When there is a malfunction in the lubrication system, abnormal oil pressure can cause excessive chain clearance, leading to noise. It is essential to inspect and repair promptly to prevent excessive clearance and chain skipping, which can damage the engine. Typically, noise caused by low oil pressure is more pronounced at idle and reduces when accelerating. 2. The timing chain of an engine wears over time with use, leading to clearance and noise during operation. Prolonged use can result in chain skipping, which can severely damage the engine. It is strongly recommended to replace it.
