Ford F150 3.5L Ecoboost Rattle Upon Start Up- Timing Chain Stretch Issues TSB

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.

Wife. Inherited 2011 F150 ecoboost. It has the dreaded timing chain issue that is covered very well on this site. I'm going to tackle it my self. Where is the best place to purchase the parts instead of the dealer ? I have found a timing chain kit from summit and also rock auto. They are the same part number from mellner.
Thx
Mike

Unless it's showing code P0016 it's not timing chain alone it's the whole phaser deal.

I think you can get the phasers from FordParts if you know the part number it'll be easy to locate otherwise some research needed.

Good luck and keep us up with yoour progress. I've got it too, but no code and I might just dealer do it since I'm yo chicken to pop it all open haha...

You could likely get away with just doing the chain and tensioner but it will likely still rattle on start up due to the phasers. And you be opening it all up again.

Rbrown has posted the whole parts list read the whole thread and search for the newest tsb that deals with phaser replacement.

That's what happens when it's real bad.

Like, better not drive it bad. Nothing good can come of this situation. Either shatter parts of phaser or your so far stretched that your way past 6 degrees on the intake cam and once you get so far out of timing when you here a ting ting ting ting, your piston smacked the valve and broken the head of the valve off. That would suck!!!!

Most people never realize they have the problem because they remote start and never listen to the truck start up.

I make it a point to remote start at least once a week when I'm standing at the grill or start with the key for this reason.

The hpfp seems to have gotten a bit louder over time, and made me a little paranoid for a bit. Haha

My dealership isn't the most competent in the service dept so they probably didn't. Already had a few other issues (if idling in parking lots there is occasionally a large jerk/jolt when shifting from 1st to 2nd). I've taken it in before and they couldn't duplicate but looks like they experienced it this time as they added a note. Sunroof broke & stuck open which was $850 3rd party to fix. Rear window broke open and couldn't close. Now this. Not to mention that I'm getting 15.0 mpg on my ecoboost while the loaner ecoboost I got pulled just over 19.

Wishing I bought the extended warranty as the various cosmetic issues that have been fixed out of pocket would have covered the cost.

DW is less than thrilled.

Ok so my truck is going in on Tuesday for TSB 16-0027 or at least what I'll be suggesting to them with my couple phone videos of cold starts. I think 16-0027 is the newest TSB related to this. Anyone else got any suggestions on what to mention to the service manager? Maybe stuff they learned by taking their truck in. That would be greatly appreciated. Thanks!

What you tell them? Did you give them a list of parts or tsb? I know Rbrown has a list additionally to what Ford replaces. Sorry for asking just want to be set when I go in

No I was one of the first to have it done way back in 2015 when they finally released the first Tsbs not for the chain but for the whole phaser issue. I took a few weeks of videos of the sound, dropped my truck off and left it. Told them to leave it overnight and start it up in the morn with the service manager and mechanic listening for it.

What TSB did you do? I hope my dealership is that obedient lol but they did a good job on that braking recall lol fast and without questions plus inspection.

15-0131 was the original phaser and chain tsb after they finally came to the realization that it wasn't just timing chains going bad. 16-0027 is the update of 15-0131.

Not 100% but I'm sure you can find a pdf of both and see the diff.

Dropped her off this morning at the Dealer for the TSB 16-0027. They first told me it is probably not the timing chain but another issue that I might have to fix. Like come on, you see the video and I can show you a bunch of comparison videos. I guess we will see if claim gets also approved under the ESP

bought my 2013 just over 2 years ago with 55k miles and 2 months in, it did it once. disappeared and then reappears once every couple months but rarely 2 days in a row. 30k miles later (86k on the clock now) and just over 2 years and I haven't heard it happen in a couple of months again. for some people it starts and gets worse, for some of us it never seems to get any worse, even on the cold days, parked uphill days, not driven for a week days, etc.

I'm not convinced anyone here or at ford actually knows what the root cause is. They'll replace some (or lots) of parts, but most of them are the same (but new) parts they took off, not revised part numbers or anything. If .1% of trucks have the problem to start and they simply change out all the parts thinking its some tolerance or unknown issue, then .01*.01% will still show the problem... not enough to really bother root causing it.

I wished mine was repaired under warranty too when it happened, but it also isn't causing me any problems or getting more frequent.

My rattle issue is finally over. My truck went to the dealer 3 times. I have 54,500 miles.

My original rattle was the chain. I would hear it after the truck sat 2+ days.

My first visit they did TSB 16-0027. It was there a few days shy of 4 weeks. About a week was wasted with them trying to hear the noise. 24 hours after getting home from the dealer I heard a rattle on startup. This time I would hear a rattle after the truck sat for 12-24 hours, but not after it sat about 36 hours. I checked my receipt against TSB 16-0027 and they replaced everything listed on the TSB.


My second visit they wasted a few days listening for the rattle. They had another Ecoboost that they completed TSB 16-0027 on. It also had a rattle after the TSB and they replaced the main chain tensioner on it. They guessed that the tensioner would fix mine too. It did not.


My third visit I dropped the truck off one evening. I went back 24 hours later and started the truck for the tech and service advisor. They both heard that rattle and stated that it was pretty loud. The tech immediately said that it was a phaser clacking. They had my truck about 2 weeks. This time I was given a loaner. They replaced both exhaust phasers (again). I have not heard a rattle since.


Mine would have been repaired the first time had it not been for a bad phaser. Everything was covered under warranty.


I also have codes P054A and P054C. Timing advance on cold start up. From what I have figured out, the codes are permanent codes because they are considered emmision codes. They technically should clear themselves after a while, but after about 1,000 miles they have not. I will be dropping the truck back off this week for the codes and rear end howling.

I thought 16-0027 includes the phasers replacement. Sorry to hear you had to do it 3 times. Hope mine comes back after it's first and for good. No one wants to deal with that much time. So far I got the "started it up and didn't hear nothing so I'm heading to my dealer tomorrow after truck sits there overnight.

So I'm back from the Dealer with my truck. She didn't rattle this morning as I was hoping she would. Anyways, the service forman said he would do it anyways based on my print out of TSB 16-0027 but he stated that Ford Corp released a new TSB in March 2017 that also asks to replace the timing chain tensioner, it's a kit. TSB for that is 17-0026. I've got a print out of it if anyone wants it.

However the kit is backordered so I've got about a week before it comes in, so I guess I get to drive my truck around with rattle still.

Plus the kid as they called him, is off for a week this week. He's the guy that does these there daily in a day.

Well, that's all to report so far. I'm going back in Wednesday of next week hopefully to get both TSBs done. 16-0027 And 17-0026.
