Guess it wasn't a fouled plug and hammering on it didn't help clean it out! Big chunk of piston blew off and wreaked havoc. Pics later when I get there. Just hope I didn't toast the crank by running it like this for a few miles. Really seemed like a fouled plug! What a dumb Azz! (to save you the trouble of posting it). Jug is toast too. Anybody got a top end take off from an 05-06 M/F 7 they want to sell? Swap meet is cleaned out.
