How to Determine if a Car Has Cylinder Scoring?

[CollinAnn]

Methods to determine if a car has cylinder scoring: When cylinder scoring occurs, the car will experience jerking sensations, and the engine will produce significant abnormal noises, with reduced RPM and noticeably decreased power. Cylinder scoring happens due to severe surface damage caused by the mutual movement of the piston and cylinder, primarily because the lubricating oil film on the moving parts is locally disrupted. The cooling efficiency of the engine's cooling system, the quantity and quality of engine oil, and the performance of the supply system are all critical factors that can lead to fatal engine damage. Causes of cylinder scoring include: 1. Excessive clearance between the piston and cylinder; 2. Insufficient lubrication between the piston and cylinder or incorrect oil selection; 3. Engine cooling system failure; 4. Low hardness or poor quality of the cylinder itself.
