Anyone have any idea what the sound in the attached video is? Possibly a pulley bearing? I was just sitting in my car at idle, and it randomly started making the video sound. Also, someone mentioned it could be a timing chain issue.

 

So there is no audio attached to your post.

Would also be helpful if you could tell us more about the car, maybe miles on the motor and some history.

 

What attached video?

Sure got that right

 

"The sound of Silence" by Disturbed?

 

Finally one hat I hear the same thing, almost, tinnitus is still in the background
