I've got my B apart for an overhaul. The top ring on one piston is completely missing, the groove filled with carbon. On the other piston the top ring is worn down so bad it is in two pieces! The pistons and bores measure good enough to reuse, but obviously the pistons need all the carbon removed, and new rings.
I've used a self cleaning oven cycle to clean carbon deposits from cast iron before, and wondered it this would damage the pistons? Any thoughts?
