Squeal, Not Belts, At Cold Start. 2006 Nissan Murano.
I have been experiencing a loud squeal at cold start. My car is a 2006 Nissan Murano SL AWD 155,000 miles. The noise only happens at cold start. I have replaced all the belts, tightened up the belt tensioner but now it doesn't sound like a belt at all. To me it sounds more like a bearing. Also I have noticed that when i am driving on the highway at 60mph and accelerate fast to pass someone there is a whining sound at high rpms, not sure if the two are related. This car has a timing chain so I have never replaced it. I attached the sound to this post, you can hear it right before the engine gets loud. I can email the file if any one would be kind enough to listen to it. Thanks in advance. Any thoughts???

Your attachment didn't come through. Lots of people will post strange noises on a YouTube and link to that.
Intake or vacuum leak?
