Does Engine Knocking Require Overhaul?

[VanGabriela]

Engine knocking does not require an overhaul. Here are specific solutions: 1. Knocking at low temperatures: If knocking sounds occur when the car starts in a cold environment and disappear as the temperature rises, this type of knocking can be temporarily ignored, and driving can continue. 2. Knocking at normal temperature: If the knocking sounds persist or become more noticeable after the engine reaches normal temperature, the owner should avoid high-speed driving, stop and inspect promptly to prevent accidents. 3. Severe cylinder damage: 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.
