I have a 2004 v6 5 speed and on occasions it will make an awful sound. I’m unaware what it is as I’ve never heard it before. Any help is good. It has made the sound both with the clutch pressed in and while sitting at idle with it out. Already replaced Idler pulley, belt, and tensioner. https://www.dropbox.com/home/Mustang?preview=Video+Apr+04,+5+35+59+PM.mov
