The video shows two cylinder liners of different quality. A high-quality liner has a smooth, uniform inner wall with a fine crosshatch pattern, even color, and no cracks or sand holes. Made of alloy cast iron, it has high hardness, making it difficult to file. Its dimensions are highly precise. In contrast, a poor-quality liner shows scratches, scuff marks, and rust spots, and its inner wall is somewhat rough and uneven.
