Could this be water pump?

No leak.

About a month or two ago, started sounding like dragging chain on cold startup. Out of nowhere. Went away in 5 seconds. Now it lasts for a bit after the idle drops, then as usual, slowly just fades away.

At first it was like a smooth chain drag but now it's a bit more chatter sounding and again, goes away in a bit of time and the car runs absolutely perfect otherwise.

This only happens when the car cools down completely. I mean totally cold.

Thoughts? Nothing in oil filter. In one year, 3 tiny bits of chain guide, but micro.
