Think my crank arm is cracked

Specialized Allez 2006 that I'm using as a commuter/touring bicycle

I think the crank arm has a crack in it. This is the best photo I can manage

http://img224.imageshack.us/i/crack.jpg/

You can't see it in the photo (camera phone), but there is a tiny little hairline crack right around where I drew the orange line.

I think it's a crack. it's along a pressure-bearing part of the bicycle. It tends to accumulate dirt, and when I run my finger along it, I can feel it, although I can't like put anything inside, and the bike still pedals as strong as every.

What should I do? About how long do I have before it falls off? Is it a problem? What should I do about replacement?

The area of the crank that you refer to should be smooth. If you can feel a ridge with your finger I would suspect a crack. Remove the crank and send it back to the manufacturer. They may cover on warranty. You will probably have to work through your LBS.

yikes, so I don't know how I can cheaply replace just the arm. Suggestions for parts suppliers?
