Mine makes a noise that closely matches your description, the difference being it occurs under gentle acceleration at low revs (not when dropping back to tickover) and more so when I'm applying a little steering.

I first noticed it after changing my EGR thermostat, a process where coolant got spilled over the pulleys / belts directly below.
