wait what? what is the cut off in 06 for the cam phaser issue and what did they change on the newer cam phasers so they dont have the issue?

I only ask as I have an 06 5.4 and I swear I can hear the cam phaser issue....its not horribly loud like I hear on some of the youtube videos but I can definitely hear it.
