Just because it's noisy doesn't mean it's knackered. The tensioner is like a plunger on a ratchet, you just need to wait til it clicks out to the next notch to take up the slack. When mine started doing it at about 26k I tried the rolling backwards thing and resetting the tensioner to no avail... Just rode it in the end and after a thousand miles or so it went away.
