Abstract: A cylinder liner assembly is disclosed for use with an engine. The cylinder liner assembly may have a liner with a hollow, generally cylindrical body extending from a top end to a bottom end along a longitudinal axis. The cylinder liner assembly may also have a seal disposed around the liner at the top end and an anti-polishing ring disposed within the top end of the liner. The anti-polishing ring may have an annular groove formed on an outer surface to provide an air gap between the anti-polishing ring and the liner. The annular groove may axially overlap at least a portion of the seal.
