2012 Civic LX Automatic Noise
I need help with a noise my car is making. This noise happens after a cold start on cold days. The sound does not occur until the car is in gear. It is louder in reverse than in drive. In the video the car is in reverse with the brakes on. The noise goes away after driving for 5 minutes or so. Any help is appreciated.

The engine moves a bit when shifting between drive and reverse but it doesn't seem like an abnormal amount. The noise sounds loudest at the left side of the engine. I put my hand on the passenger side motor mount and the vibration feels much less on the mount than on the engine itself. The mount vibrates only very slightly. The vibration is dampened by the mount. Could it be a pulley bearing? See the new video for noise in the engine compartment.

For anyone who reads this in the future I narrowed the issue to the belt tensioner. I replaced the tensioner and the belt and the noise is gone.
