I have a spare set of JE pistons for a 7m and was wondering what you guys think about this piston. Skirt touched when a plug dropped it's ceramic into the cylinder and got down around the side and broke a rin. It weighs within two decimal places of a gram to the others and seems to have no ring or face damage at all. If I did use it in the future it would be going into a freshly machined up block.
