I just discovered my timing belt was missing a tooth the other day (!) while I was screwing around with my car (off the road for about a year now). I am fixing it up to be a good daily driver again, so of course I am now replacing the damaged belt.

While looking at the new belt, I remembered that the new K series engines use timing chains, so I got to thinking why Honda would change over to a timing chain. Which is better and what are the advantages of both? I am guessing the chain because, well, it's not reinforced rubber.
