oh oh I may have #2 exhaust valve leak.... took headers off yesterday and 1,3,4 were all nice and white.. #2 was black and sooty..I guess the next step is pour all that carbon eating additive stuff in and if that doesn't help (ie if there is carbon build up preventing a good seal, not sure if that really happens though) if that doesn't work then get ready to get dirty...
