Hi all,
I just got my '05 FX4 back from the dealer today along with some disturbing news. I originally took it in for an oil change, door alignment, hood vibration and lack of power. Well they got everything fixed with the exception of the lack of power issue. There report is that I need the Cam Phasers changed to get my power back. Now when I took the truck in it was quiet and now after the service it has a valvetrain rattle. What did they do? Why do I have the rattle?
I think they tried a reflash to solve the power issue (they wouldn't confirm this) and after that is when the rattle started. They said it was this way when they raised the hood but if it was I never heard it. Maybe I am paying more attention to it after they pointed it out, who knows. Anyway, what am I in for with the Cam Phaser swap? Will this eliminate my power issue? My whole issue with the lack of power was that the engine was very sluggish until around 4500 rpm. Does this sound like the Cam Phasers? My wifes'03 Explorer with the 4.6 runs circles around me!
Ok I'm thru rambling, someone enlighten me about these things and what they do.

Thanks

 

Josh,

not sure about the cam phase sensor, thank goodness. What was the reason for the door alignment. I have a clicking/popping noise at the B pillar and I belive it needs alignment they stated that they did not hear it the first time I took it in and the door alignment was ok. So why check the door alignment if they did not hear it...go figure.

Oh...2004 Screw, FX4 and it is the front door.

 

The body lines were off. It was really obvious so they had no choice. Mine never popped or made any sounds it just bugged the heck out of me everytime I got in it so I had it adjusted. Mine was the front drivers door also.

 

I suspect you are right, you just never had the noise called to your attention. It happens that way all the time.

If the CP is buggered, then yeah, you could be getting low power from it. Basicly it changes the cam timing by RPM, according to Ford's little info piece.
Thus allowing the cam to make more power at different RPMs. A failure could give you exactly the problem you discribe.
Good Luck,
Chris

 

I have 8,400 miles on mine and at my 4,000 mile oil change is when I started to hear valve train "chatter" noise also. I work at the FOCUS plant and I'm hearing the dealers are possible using a different grade oil than what was put in at the factory. Can't confirm. I hope thats all it is! I to wonder if the "cam phasers" will make a difference to, mine is still sluggish up to 4500rpm after my reflash. Really considering doing the Diablo tuner to elimanate all and get that extra 40+ hourses with a better trans shift...........{p.s.}I feel your pain! I have a rattle in the over head liner above the passenger side, {goes away when rear hanger hooks are pulled on[?]} and center dash tray rattles when interior warms up, other than that my tail lights are STILL RED!......Thanx FORD for a good nights rest. HA!!!!

 

Thanks Guys, how long should a repair like this take?
