Which risk increases when an internal combustion engine piston excessively rocks within the cylinder bore?

💡 Explanation

When piston rocking exceeds designed tolerances, increased side loading occurs because the piston skirt cannot maintain uniform contact with the cylinder wall, leading to localized abrasion and breakdown of the oil film, thus accelerating wear and scuffing. Therefore cylinder wall damage results, rather than detonation, float, or pump cavitation which involve different engine components and mechanisms.
