The cylinder bore wall includes a liner stop mechanism to support a liner in the cylinder bore. The engine block has an outer cylinder block wall that is exterior to the cylinder bore wall. The outer cylinder block wall includes at least one rib located relative to the liner stop mechanism to reduce rotation and buckling of the liner during operation of the engine.
