Just to let everyone know the sound will more than likely come back... at least the normal noises these phasers make.

Mines at 100k and the noise has always been there. Its hasnt gotten any worse and from the little drag races I have done it does not affect performance. Now some may be worse than others but I always considered mine on the loud side. Some peolple may be over reacting on the urgency of the repair fact is that if it truly is the famous ticking then in my experience it is not detremental to longevity or performance....knock on wood lol.

Cam phasers do make noise on tip in, this is normal. Most engine have some sort of noise at idle, I would not be worried if you can only hear it outside beside the engine or in a drive thru.
This repair is done when the noise is "Diesel-ish"
some of these loud tick you hear on the youtube videos... this is not "normal"
and the 5.4 is not suppose to make this noise!!

After the repair, this adresses a few reasons I have seen them tick.

The phasesrs are not aways worn. The phasers and the chains will make noise if the oil pressure is low due to blown seals or the chain is slack causing slap.

You guys know your trucks. obviously take this guide with a grain of salt and diagnose the problem before starting anything, so not to waste yoiu time and money

Agree that these engines do make ticking noises even when running perfectly, the chances are its the injectors and a little phaser or valvetrain noise. Having had the major ticking and chain slapping noise and then replacing everything, the noise I am left with is the injectors......this is no problem. Worn chains, tensioners, guides, phasers, lifters and rockers are a problem and your shouldn't delay too long in sorting this out......and as mentioned, don't just do the phasers, its false ecconomy and a big job to get that far into the engine.

I just ran my truck up to a place north of Dallas from Houston after doing the timing gear and got 15mpg when the same journey 2 months ago saw 12mpg......probably timing related based on crap hydraulics!

a pic of a good and bad rocker - but as S_Vares states - change them all if you are taking on this job, same with lifters! At 100K+ miles, its good sense to do this job once, if want another 100k+ out of the truck!

I do believe ford wouldn't allow these engines roll out of the factory. With excessive ticking or banging. Unless Theres a conspiracy . With a parts manufacture for that motor ... I. Myself am gonna do this job mentioned. My chains are slack. And do have a single tick at how idle and chain noise also. 145k on it. I work for a company that supplys. Ford with power seat components for there f150. And nothing bad passes out the door. Or production stops. Or we get fined from the company we r supplying . Just my opinion

Yes! this is a problem coming on some higher milage 5.4
Mine is quiet and smooth at 100,000miles but im doing the chains this summer as its not a horrible job, and will save me problems in the future.

Ive got it down to about 5 hours including refilling ac now.
