My '07 Pathfinder whines quite a bit when I rev the engine (see above video). I just changed a bad alternator and belt tensioner, so those are ruled out. Does this sound like the classic secondary timing chain whine to you? I've brought it to a few places for professional opinions and none of them seem concerned about the noise, oddly. Thanks for your input!
