hehe... well I mean really... This black stuff that comes out... It's pretty good size strip, so if it were anything to worry about like oil, and u ran it all day today, stopped and got groceries, picked up the friends, etc. you'd pull out the dipstick tomorrow and it would be bare. ;-)

P.S. I just saw on another thread people running ATF through their intake manifold and it supposedly cleans out all that shizz we're talking about... personally, I'll just let it fly out when I give it the gas LOL
