Porsche water cooled engine cylinder walls are specially treated. When replacing piston rings, DO NOT use glaze breaking equipment on the cylinder walls, since it will cause damage to the cylinder wall surface. If the cylinders are not worn or damaged, wipe them clean with a lint-free towel and oil lightly before installing piston with new piston rings.
