I read a couple articles on this matter and tests have shown it is better to NOT hone IF you use cast iron rings because the rings will do it during the break in process. They say that by roughing up that nice smooth surface only creates valleys that will later contaminate the engine with microparticles. It says that the rings will now smooth the valleys out causing the cylinder to grow larger and the piston being the same size creating exsessive clearance. So can a proper break-in with iron rings make up for not honing and cause less damage over time? I bought Hastings rings. They are made of Moly, what is moly, Is it a form of iron? I just never honed before and I don't want to mess anything up and this article has me thinking twice. Need opinions!
