I mean mine sounds so bad that it is very loud and sounds like a diesel engine only at warm idle, ( peole have asked if it is )after 1200 rpm its fine? no sound. So I know its the phasers and the check eng light is not on.
I just want to know if I should spend the money to get them replaced. Is there a updated cam phaser from the stock one that I have now in my 04 5.4
sorry to ressurect an old thread but another reason to have them replaced is the power difference... i drove a friend's 5.4 with good cam phasers and its a huge difference... on the highway mine always has to downshift to get the power it needs but his just has it there and also for around town his seemed way torque-ier to the point where i was getting way more into the gas for the same power benefits (like i'd be at a third to half pedal for his quarter pedal) so i'd recommend doing them... as soon as i can afford it i'm doing mine
