It's the flux capacitor.
Where is the noise coming from? Take a long screwdriver and touch it to the valve cover on start up on that side. See what you can hear. These engines are famous for cold start piston slap, which isn't really a big deal, but it could also be a lifter if it's something that quiets down - which would be a big deal. Need more info.

Haha yeah our 2002 Escalade with the 6.0 LQ9 does it really bad on a cold start for like 15-20 seconds, but it's done it since we got it and now at 230k.... meh. It lives. It's annoying though.
