What Causes Engine Chain Noise?

[LaEli]

Engine chain noise is caused by delayed oil changes, damaged oil pumps, lack of tension in the tensioning device, etc. Delayed oil changes: Failure to change engine oil promptly leads to noise. The chain requires oil lubrication, and delayed oil changes will cause chain noise. Replace the oil to resolve the issue. Damaged oil pump: Check for oil pump damage, which can result in insufficient oil supply, preventing timely lubrication of the timing chain and causing noise. Replace or repair the oil pump. Lack of tension in the tensioning device: This can be due to insufficient tension in the chain tensioning device, stretched timing chain, abnormal wear of the guide chain plate, or damaged timing sprockets. Replace the specific mechanical component that is damaged.
