I first heard this a few years ago on a really cold morning (15-20* F), and it sounds just like a tea kettle going off. It started again last year, so i replaced my idler pulley and, oddly enough, the noise went away...
Until this winter time, and its worse than ever. I replaced the idler pulley again, but i made no change. The noise goes away above roughly 60*F outside, but anything cooler than that the noise is pretty constant.
I checked all the vacuum lines and connectors, which all looked good. I also checked the torque on the rearward manifold bolts, which were in spec. I checked for cracks in the manifold too, but didn't see any. I'm at a loss here, and this noise is very embarrasing....people actually stare. help!
