I'm thinking that it might be the BB. I didn't have the right tool to install it myself, so I had my lbs do it, but I recall that it was kinda oily when it was installed. Seeing as it cost be five bucks to have it installed, and I really don't feel like disassembling my crank, would it matter if I just left it alone. Is it possible that it would dry out over time?

Oh, and apparently the chain line is fine. The guy at the bike shop said that it was a pretty normal amount of noise. They had a pista in the shop and it made the same amount of noise, so I'm not worried about it anymore.
