roussseau, a new headset is so reasonably priced, even a very good one. Just replace the whole thing, and be done with it. I like the value in Cane Creek, even their cheapest ones are excellent, but the "40" series the definitely the sweet spot in the line. The only help you would need with this would be replacing the crown race. That is the only thing that requires tools that you may not have. I know this seems like a cop out, but sometimes new parts are just the most sensible fix, especially when they are not terribly pricey. The bike will look nicer too with a new headset. Don't fret that it won't say Bianchi. Stuff happens.
