click-click-click sound when engine is cold

[RougeTrooper]

I have noticed this for sometime now, when my engine is cold and I just start it I hear a click-click sound, you can hear it from 8-10 feet away.

Once I drive for about 2 miles, I do not hear a thing anymore at ALL. Took it to the dealer, of course the only way I can replicate this is to leave the engine cold for 8-9 hours, dealer said, 'yeah it's normal'

The sound is very low and not as loud as you would get say if experiencing a piston slap...

So do you guys have the same experience? 2007, 3.0.
