Are you using that Dow Corning Molykote on the skirts? How is it applied? When I worked with them on a development project in a previous life as a piston engineer, they were promoting a screen printing process. We found that getting the coating to stay there over the long haul was difficult, although it has made its way into some production programs. Gimmick or true benefit, I'm not really sure. Any opinion/data on this? In my opinion getting the ovality and profile of the skirt right are more important. Since the skirt/cylinder interface operates under hydrodynamic lubrication once the engine is running, frictional loss is a function of the oil viscosity (shearing forces) as long as there is no hard contact due to a profile problem. Therefore the only benefit of the skirt coating should be on startup, or if the shape of the skirt is marginal to begin with. I don't mean to bash your process- those are just my thoughts, based on what my Brazilian friends at Metal Leve taught me. Regards, Bob
