cam phaser replacement...do it yourself?
I know my 04 F150 5.4 has the cam phaser ticking and I suspect it is the cause of the lack of power. I have worked on engines since I was 16 off and on, 38 now. I have never worked on an engine with these cam phasers and to be honest don't even know what they look like.
Can the average Joe replace their's? I would like to know the cost of the parts and if there are any special tools required. Any pictures are also a great help.
Oh, warranty is up so I am on the hook for this repair.
