What is the recommended grit stone rating for glazing-busting a liner with a hone?

The recommended grit stone rating for glazing-busting a liner with a hone is in the range of 200 to 250. This grit size is suitable for effectively removing the glaze from the cylinder liner while still providing a finish that allows for good oil retention and satisfactory sealing with the piston rings.

Using a finer grit, such as those in the higher ranges, may not adequately remove the hardened surface layer and could lead to issues with ring seating or increased engine wear. Conversely, using a coarser grit might remove too much material, affecting the overall dimensions and leading to improper sealing and increased oil consumption. The 200 to 250 grit range strikes the right balance between efficiency in removing the glaze and maintaining the integrity of the liner surface.
