I don't believe it's the timing chain at all. Usually when they go or even skip a tooth, your car would be backfiring and generally running poorly. Since you've had this noise for nearly 5,000 miles I would say it's not that. I would go back over the bolts for the harmonic balancer and make sure they're torqued to spec as that's the only thing I could think of. It's a very unique noise that doesn't sound serious. Do you have a mechanics stethoscope?

If you take the oil pan off, you can check slack on the timing chain from below. You might even be able to see the tensioner, IIRC. Maybe even see the alignment dots...?
You'll spend a good day doing the timing cover.

Any developments?. We are curious to find out what the problem turned out to be.
