Ok so some may know about this some may not but it is something that is coming on strong with many showings at dealerships across America. So as most know it is timing chains that are prematurely stretching causing this startup noise. The news is that there is updated parts out there to address this and Ford now has a TSB on this issue formally admitting to it being a common problem. I go over it all in this video. There is also a link to just how it sounds in the description of the video on youtube. Hopefully more dealers will be willing to dive into the engine with some guidance from Ford now.

So how much did it cost to get this repaired?

$3000 at the dealership. Free when under warranty.
Mine has rattled 3 - 4 times since I got it back. Today was the loudest I've heard it since getting it back. It doesn't rattle as long as it did before having the TSB done, but it still rattles for a split second. Now it seems to do it when it's warm, and not cold. I usually hear it 8 - 24 hours after letting the truck sit. Before the TSB I would hear it after 2 or 3 days. I'm a little mind blown that I'm still getting a rattle. Now it does it when the temp is 50F+ as opposed to below 50F before.
I checked the TSB parts list with my receipt and everything matches.

I honestly am starting to think some of these dealership service departments are doing something wrong when they perform the work. Perhaps they aren't cleaning something properly, or they are overlooking something that should be cleaned. Something doesn't seem right. If repaired properly the condition should not come back so quickly
From what I gather I'm the only one that's had a problem with the latest TSB. According to my receipt they replaced everything that the latest TSB shows. I'm thinking either part failure or installer error. The service advisor told me their best engine guy did my repair, so I'm not sure what to think. Even another guy at the desk bragged. I'm having the same problem as before the TSB, but under different conditions, and it's not as loud yet. Should I open up a case with Ford Corporate?

I did hear that some of the guys were saying while it's all open( doing the repair) . To go ahead and have them replace the tensioner.
I heard this after I had mine fixed, but also haven't had a problem since the fix.
I've also read that too, but I took it as a preventive. I just got off the phone with the service advisor. I'll be taking the truck Thursday night and the guy said they would look at it Friday.

The primary timing chain tensioner has to be replaced. It is an updated part and goes hand in hand with the primary tensioner arm. When one is changed and updated, so is the other.
Does this TSB call for changing secondary timing chains, secondary tensioners and guides, and exhaust cam phasers with 4 new VCT solenoids?
Those exhaust phasers should 100% be changed regardless what ford says. While it's open tell them to change them and pay them the money to. Same thing with the VCT solenoids. Those solenoids are what controls the oil flow. If they are not replaced and are at all blocking any oil flow, and not working at 100%, you will always have the problem with your phasers.

Only the primary chain and parts were replaced. I dont know if they did the tensioner. I would have to look later and see. If you go back on a few of my posts you can see the parts that were replaced on my receipt.
None of the secondary chain or parts were replaced. If I realized the first time they needed to be replaced I would've had them do it. Maybe they'll figure out that all those parts need to be replaced too.

A lot of those parts are not part of the TSB. In my opinion they should be replaced, and if it were me if this helps anyone, I would either pay to have them install the rest of that list I mentioned while they are in there. It isn't but another hour at most of labor, and you technically could buy the parts online cheap and supply them. Those VCT solenoids are really important to how the system works.
Are you talking about the secondary chain and parts?
Could you possibly make me a list of the rest of the parts that should be replaced? Once the dealer tells me what they plan on doing I'll see about having the secondary chain and parts replaced. I'm hoping they figure out themselves the secondary chain and parts need to be replaced now. I'm still under warranty which is why I hope they figure it out themselves.

Would you mind sharing that list here? I'd be interested in having it for future reference if I ever need it.

Ya, that's not a repair if it's still happening.
How many mile after the repair???
Thats clearly the sound mine made before. And after my repair it has been fine. No noise. BS, take it back in.

A guy who I work with had the TSB done. He says he still gets the rattle. But they won't do anything unless the P0016 code comes back.
There is a guy on f150forum that has had the rattle for a good chunk of miles and never has an issue other than the rattle. His user name is maplelakeduckslayer. Read his posts.

I drove home 13 miles from the dealership. I parked the truck for 24 hours. I cranked it up and heard the rattle. I never had the engine light come on and the dealer still did the TSB.
Before the repair the rattle was worse below 50F. And I would get it after the truck sat more than 2 days. Now I'm getting it with Temps above 50F and I'm getting it after the truck sits 12 - 24 hours. My symptoms are now opposite of what they were before the repair.
If they truly replaced all the parts in the TSB (receipt shows they did), then I'm thinking something else is causing the rattle, a faulty part was installed, or installer error.
I don't think they would lie about what was installed. I would think they would get in trouble for that.
I'll check out that guy's posts when I'm on a computer.
