It's probably either the tensioner or the guide rail, and suggests some mileage. The guide rail keep the chain quiet once it wears-- on the earlier duplex chain engines, the worn chain would announce itself by rattling against the timing chain cover and create noise and aluminium shavings. It isn't going to get better.

No big hurry, but don't forget about it...
