Just noticed a fuel leak that appears to be coming from around the throttle shaft. If anyone has any tips for replacing the throttle shaft seal, I would be most appreciative. Also, I have been having some problems with fuel filters becoming plugged prematurely (less than 6000 miles). After cutting the filter open to investigate, along with the normal dirt one would expect to find, there is some other debris that resembles white/silver paint flecks. It won't stick to a magnet, so it must not be a ferrous metal, if it's metal at all. I would really like to know what this crap is. Any input is appreciated. Thanks.
