What Does Cylinder Scuffing Mean?

[ClaireAnn]

Cylinder scuffing refers to an impact failure between the piston and cylinder liner in an internal combustion engine. The causes of cylinder scuffing include: 1. Severe lack of lubrication oil; 2. Drastic changes in the thermal expansion coefficient of metal objects; 3. Excessive mechanical lubrication clearance between the piston and cylinder wall; 4. Poor quality cylinder gasket with insufficient surface flatness; 5. Improper driving habits, such as long-term aggressive driving. Symptoms of cylinder scuffing include: 1. Engine weakness during driving, difficulty in acceleration, and air leakage sounds at the joint between the cylinder head and cylinder block; 2. One or two cylinders not working, with bubbles appearing at the radiator filler opening; 3. Milky white engine oil when checking with the dipstick; 4. Continuous water droplets flowing from the exhaust pipe.
