Looking for just one used piston in sound shape for 420SEL engine cause have problem with one cylinder but not sure the cause of very low compression. Valves I can buy individually but pistons and rings are sold only in sets and very pricey. So, if anyone out there has done an engine rebuilt replacing pistons, perhaps you can help me. Many thanks.
