Mine makes a faint whistling noise too. It first I thought it was the EGR system bleeding out of my Cusco catch tank, but not sure.
I am suspecting that its either that or some high capacity line of 4D-S system. Regardless, I doubt it is a malfunction of any sort. I'll keep posted if you I hear anything from Toyota side of things.
