Future information.ation for anyone attempting to replace timing chains and cam phasers on the 5.4 3v, you DO NOT need the cam lock tool. All you need is a couple good sets of large vice grips and lock them down directly behind the phaser on the camshaft. As long as youre chains both the chains and phasers. Here are some pics so u can see how to align the vice grips. Hope this helps anyone
