What Causes Cylinder Scoring in Cars?
1 Answers
Cylinder scoring in cars can be attributed to the following reasons: 1. Overheating of the engine due to insufficient coolant in the cooling system, preventing proper circulation and heat dissipation, leading to high engine temperatures. 2. Poor performance of the engine lubrication system. 3. Improper clearance between the piston and cylinder liner or other components during engine assembly, or misalignment. 4. Unsuitable material quality or improper heat treatment. 5. Insufficient or degraded lubricating oil causing poor lubrication. 6. Blind removal of the thermostat, blocking the small circulation channel, resulting in excessively low water temperature. Below are additional tips for preventing cylinder scoring: 1. Ensure proper break-in for new or overhauled engines. 2. Follow the manufacturer's instructions to correctly set the clearance between the piston skirt and cylinder liner, as well as the piston ring end and side gaps. 3. Monitor the engine water temperature while driving. 4. Operate the engine appropriately, avoiding overloading, unnecessary throttle revving, and rapid starts. 5. Replace the air filter at scheduled intervals. 6. Maintain the lubrication system to prevent mechanical impurities and carbon deposits from mixing with the oil and accelerating cylinder liner wear.
