Basically the coating started coming off the pistons. Everything was done including the break in procedure as per the instructions. When the guy who did the motor contacted the piston manufacture they said "bad rings" We'll send you out a new set. It almost looked like the coating was coming off in bits. Not good for any lubrication. Going to bite the bullet and put in a new set of non coated pistons. Suppositley they ask for the cylinder size and coat the pistons to match the bore. Then you take scotchbrite and lightly sand the piston to just fit into the cylinders. The coating then wears slightly to have proper piston clearance. I think the coating itself is a good idea but with proper clearance and a minimum amount of coating on the piston. It almost looks like it was put on real thick.
