First off, I'm sorry for yet another "what is this noise?" post! I've searched high and low around the interwebs and have not found anything that quite compares to what I'm hearing. Thus far, this hasn't correlated to any problems, but I'm going to be tearing into things to identify [yet another] charging issue later today so thought it'd be a good time to try getting to the bottom of this as well.
Rather than waste too much time with a description here, I've uploaded a recording to YouTube. Any ideas as to what this is will be greatly appreciated. In this video, you'll hear the noise at 2 seconds, 10 seconds and again at about the 30 second mark.
A few quick thoughts: It sounds like it's coming from external to the engine, but could also perhaps be something from the timing chains? It's rhythmic when it occurs, and typically lasts less than 10 "clicks". Alternator, water pump, idler and tensioner pulleys are all new in last 6 months.
