My truck has this problem and I hate the noise. It pisses me off to think that ford would screw up on something and charge 2000 plus to repair it. And if you do get them fixed their is a chance the probem will come back. Ill just say if I wsa going to go buy and used f150 tomorrow I would get an 07 or an 08.

my '08 that was leased had a wicked cam phaser tick at 35k miles. when that lease was up i was test driving 11th gens to buy and an '07 i was looking at had a mean tick also.

now my '05 with 80k is quiet. knock on wood.

so from my experience any of the 04-08's can do it.

here's what ya need-

also i talked to the dealer today and he said that he bought it form a different dealer that had put a new motor in it at about 75k and now it has 148k i'm not 100 % sure why they put the new motor in but he did say that the motor doesn't make a sound

I've been doin some reading and because of this cam phaser issue people are having to replace there motors at 42,000 miles!!!! Unbelievable. Does anyone know if the phaser limiting kit from comp actually works and saves your motor from destruction?

So u used the lockout limiter or whatever its called from comp and it has worked? Part number and more details on cost and install please!

I saw a thread on one of the forums regarding this a while back. IIRC someone had just done it and said you had to have a custom tune or the computer will start throwing codes. Sorry - don't remember any more on it or which specific website it was on but it was one relating to F150's.

I just did cam phaser lockouts about 2 weeks ago. So far they are doing the job. There are a couple of things I don't like. 1. I have lost about 2mpg. 2. I lost a little bit of top end power. (Over 2500rpm) 3. I have a check engine lite for cam timing. I put black tape over the lite.(lol) The good news is the truck runs a lot smoother and is lots quieter. I also did the work myself, it isn't as hard as ford wants you to think it is. Let me know if you have any questions.

The ignition timing has to be changed if you use a lockout.

The "phaser" is a device that changes the timing of the valves, when you need/want power/torque the valve timing is advanced (they open sooner and close later), and when idling or light load/throttle the valve timing is retarded (open and close later). The advanced valve timing as you might guess allows more fuel and air into the engine which equals less mpg, and retarded is more fuel efficient, but less power.

This is all controlled by the phaser. If you lock it out I "think" (could be wrong) it puts the valves in the advanced timing position and because of that you also need to change the ignition timing to match. It also means you will always have less mpg.

Last points I want to make, the phaser is powered by oil pressure. The driver side phaser actually is like the last point in the top of the engine that receives oil - it goes from the passenger front to the rear around to the rear of the driver side and to the front. So, the driver side phaser is usually the one that starts having issues. Regular oil changes using the correct viscosity usually is the key to keeping that phaser charged with pressure.

Actually one last point. Full synthetic oil has "thicker" and more consistent molecules. So that kind of oil can be bad for newer engines or parts in the engines that have very tight clearances and tolerances. I know folks think full synthetic is great stuff, and it is in a lot of ways, but it can also be bad for certain aspects of engines. I always use blended oils in engines so that I can be sure everything is getting good pressure and oil while still giving the benefits of what synthetic oil brings to the table.

Edit: just noticed this an old thread, but it is linked to from a stickied thread so hopefully this is helpful to others.
