i might be wrong and forgive me if i am but im pretty sure thats a sign of pre ignition so the timings out and will soon hole the piston if it carries on like that, but await the reply of more seasoned professionals

dont confuse matters here ,it has only siezed and burnt the top of your piston because of the air leak and hence lean mixture ...presuming you had your timing set as malossi recomend 14 btdc
