How to Solve the Right Engine Knocking Sound?

[BrandonLee]

Solutions for engine knocking are as follows: Knocking sound disappears as temperature rises: When the car starts, knocking sounds occur in low-temperature conditions. If the sound disappears as the temperature rises, this type of knocking can be temporarily ignored, and driving can continue. Knocking sound becomes more noticeable at normal temperature: If the knocking sound does not disappear but becomes more noticeable after the engine reaches normal temperature, the owner should avoid high-speed driving, stop and inspect promptly to prevent traffic accidents. Replace cylinder liner, piston, and piston rings: If after removing the cylinder head and extracting the piston, severe cylinder ovality, scoring, or excessive clearance between the piston and cylinder is found, replacement is necessary. Replace the cylinder liner, piston, and piston rings. Replace promptly: If the connecting rod is found to be deformed, it should be replaced as soon as possible.
