What Causes Cylinder Scoring in New Cars?
1 Answers
Cylinder scoring in new cars can be attributed to the following reasons: Excessive impurities in engine oil: If there is an issue with the filtration system of the oil delivery system, such as a malfunctioning oil filter or suction filter, allowing contaminated oil to reach the cylinders can result in cylinder scoring. Engine problems: Overheating of the engine due to leaks or insufficient coolant that is not replenished in time; excessively low engine oil levels, leading to loss of cylinder sealing and lubrication. Piston issues: Broken piston rings scratching the cylinder walls; detached piston pin circlips scratching the cylinder walls; piston rings stuck in the grooves due to carbon deposits, losing their sealing function; protruding piston pins scratching the cylinder walls.
