Hi there, was the plug to long? Or the incorrect heat range? If to long, it may have fouled a valve depending on the configuration of the combustion chamber. Or struck the piston. Is the plug broken? There may be bits of ceramic insulator in the cylinder, you may have damaged a valve or at worst cracked a piston. Do a compression test to check valves, and ask you mechanic if they have a borescope to view into the cylinder ans inspect for any damage,
