i gotta friend in the chicagoland area that refreshens older engines and cleans them up very well. after i threw a valve into my piston (at around 12x,xxx miles) he helped me after i took it out. wasnt too bad. mine lasted that long until i started to manually shift my auto and i forgot to shift outta second quick enough and she was tappin like 6k for a few seconds and wham, there goes the valve into the freakin piston
