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.

Nope 80k or emissions won't cover it. 100% sure on that one. I tried before, even when I didn't have the noise just to make sure I had 20k till 80k if it happened without buying the ESP. Everyone at Ford said nope and on forums, got the TSB... now I'm good till 138k

Now here he says 60k.
. So your right.


2012 screw 3.5L
That's because it's a bit confusing when you look at the TSB, it states about emission and TSB, etc... on it. So some thought that it wpuupd be covered by the emission warranty but it's not even close. Even with a TSB, still need corporate approval, it's not that easy drive in the dealership and get it fixed under ESP.

I'm hoping that corporate approves it all under my ESP since my dealer is doing both TSBs which is like 20 hours, and 25 parts in total to replace and get, which brings costs probably over $4000 if I paid for it. Fingers crossed I guess, if not, then I'll be looking at another brand.

With the new TSB for the tensioner being redesigned, which doesn't seem no part store has it and if they do it's on backorder from Ford. So it's backorder for few weeks if you gonna go in and try to fix it with the latest TSB I posted.

I wonder how different this one is vs what was put in. Are these tensioners the ones they got in 2nd gen of ecoboost engines.

Does anyone know the difference between gen 1 and gen 2 of these engines? Big difference? Completely different monsters or what?

Food for thought. I have a slightly sloped driveway I normally park facing uphill and my truck has been making the rattle for 6 months (2011 w/57k miles). This week I backed in so the engine was facing down and the rattle has not happened since doing that. I am not sure of the mechanics of the oil pickup, pump or flow to the tensioner but this certainly made a difference with my truck.

What oil filter is installed in your truck?

So the truck is in, will be done tomorrow. I'll let you guys know how she's running and if the sound comes back in the next day or so. My MPGs fell quite a bit from 18 down to like 14 and below. Even with a tune, I wasn't able to go past 15, even without heavy foot. So it might of been getting worse.

Btw, RBrown ... the shop manager said he compared the photos and part numbers in the photos and the new TSB with the tensioner, does seem like the correct one is going in from your photos. Thank you for sending those.

Ok so got a call, my truck is ready and she got new parts in her, new oil, new coolant, they even refilled the refrigerant? ?

Anyways and she got a free wash. To be honest, I can't wait to get it back. They gave me a loner for the two days, and it's a 2017 F150 base model. Yup, base as base as they get. I'm sorry but I got to vent. It's nice with that fresh new car smell, but that's about it. I don't know why but the interior just doesn't feel right to me in this truck, 2011-2015, is better. Also, v6, they gave me v6 with nothing else. No turbos, no vroom vroom... plain v6. She screams from every stop and usually my body goes forward faster then the truck, since I'm use to getting my rear planted into the seat when I floor it, not the other way with me almost smashing my face into the windshield at the first stop I made and flooring it. I went but the truck lagged behind. Lol...

Ok vent over, its new truck, new smell, feels new, looks new ... that's all it has going for it in my books. I'm sure it's because it's base model with nothing ? not very impressed and specially since the service manager kept saying I should look at the new.ones, maybe I can trade my 11 in.

No thank you! I love my 11 even more now. Thanks Ford ?

That's the same motor as the 3.5l non turbo or the new 3.7l. Same motors small difference like DI, bore size, etc.. but the 2017 3.5 non turbo is the gen 1 but 3.5l

I got mine back yesterday for codes P054A and P054C. They told me that the codes are from all the work that has been done on the timing (They had to open up the motor 3 times). I was told they would have to clear themselves since they are permanent codes and that the computer has to relearn the truck.

Hmmm... that's interesting, I got mine done and received back yesterday. No codes for me, not yet. She's already tuned back haha. However I'm still getting the boost dump and more detonation going on with the tune. Anyone got any ideas? Gapped plugs recently at .28 and not to hijack for not related.

After lightly browsing through the thread (63 pages is a lot to take in) , I have questions. My 12 just started this within the last month or so, and I am at 126xxx miles. I seem to notice it moreso in the mornings, than I do in the afternoons. I am wondering what kind of time frame I have to get this fixed. It is not throwing any codes as of yet. Also, how much am I looking to fork out to have this done? For those of you out of warranty, did you take it to a dealership or to an independent shop? This is our only vehicle, and with my limited knowledge and lack of garage, I wont even consider tackling this on my own. Thanks,

Hard to tell in regards to timeline and when the error codes will come out. If you look at my post, I've had this very recently done, couple days ago, I've had no errors and from what I know you get errors when you are 6+ degrees. Mine seems it was at +12 degrees and I still had no codes but loud rattle in mornings after first time starting the truck each mornings. I honestly think I could hear it all the time though also, just enough to hear the chain.

That said, I got extended warranty for this reason. Normally, if you do it yoiurself I think it's about $1300 in parts alone. If you take it to any shop it's $2000 - $4000, depending on labour charges. Ford dealer, depends also, some will be like 3200 for the job, some more, depending what you ask to have changed. Since they are in there, I would change a few more parts then just the phasers and chain, like water pump. Might be few hundred to do that as extra.

My dealer showed me the invoice that was going to corporate under warranty, so the dealer could get paid for the service done. Since they were doing both TSB under warranty, newst TSB and 6 months old TSB, the cost to corporate from dealer was $4800. That's before they labeled an additional time needed for phasers.

Hope that helps put a bit perspective on it. I know RBrown will shine here even more with costs since he suggest I should do it myself just didn't have the guts. Lol

Wow, thats nuts. I am going to be screwed if it leaves me stranded...With that being said, when did you get the extended warranty? Was it through ford or a third party? Now im stressed...

Sorry man. I got my truck used with 63k, before the noise started, I got worried from reading all the stories on here. As much as I can fix and take things apart, wasn't going to take a chance on a 12k motor to do it. That said, I looked into Ford extended warranty and found a good source from all of them to be the cheapest (not 3rd party, direct ford) took the power train since it covered more then I'd be ok at fixing or replacing and took it. My noise started at 74k, good I got the warranty.

So really, so far my warranty cost me $1200 bucks and I'm covered till 134000 miles but already saved and it paid for itself.

It's stressful and I know, I can't afford to pay $600 a month for a 2018 so this one has about 8 more years to go before I look at used again. Now if the motor takes a dump before 134000 miles I'm good because I'll pay $50 for a $12k motor plus labor. That's if they don't stick me with it being my fault. So far, my dealer has been great suggesting to do both TSBs and telling me about the newest one that came out few weeks ago.

However since you've read this thread, you probably know that sometimes dealerships or corporate will work with you to pay half for the job or pay for even a bit, always helps.

I saw earlier on this thread that pumping the gas before starting got the oil flowing, and eliminating the rattle. Is this true, or did i misread? If so, how much do you pump the gas?

Also, I've started looking at extended service plans, what has everyone bought and were they any good?

It would save you from a big cost of this repair plus get little bit coverage. 3rd party ones might be pain for warranty.

I'd also make sure when the inspector for Ford warranty comes for a 15 minute drive with you, that you'd have nothing else rattling lol. Start it before he comes if it happens on start up.

My 2011 F150 currently has the dreaded rattle at start up issue. Last week I was finally able to capture it twice in videos on my phone so I made an appointment with the selling dealer and dropped it off Friday afternoon with hopes that it would make the sound on start up Monday morning. They did not hear the noise and have not been able to get it to do it each day since (they still have my truck). I showed them the videos but they still are insisting they hear it in person. I purchased the extended service plan at the time of sale and it expires in August. I'm started to wonder what my next move should be. Has anyone had one of these fixed under the extended service plan? Was it a pain to get them to do it? Any advice on what my next move should be?

I actually had smooth sailing with mine. I took it in with bunch of videos, just to be ready. They kept it overnight to hear it, I made sure I was there. No sound. But the service shop forman said he knows what I'm talking about and I jumped right away on the whole talk about the 16-0027 TSB. Well he said, there's a new TSB just for the tensioner and bracket. I was like ohh really. He said yup, so what we will do is we will do both TSBs, the one that replaces the chain, phasers, etc... and then the latest one too, that does the tensioner.

He said parts are on backorder so it'll be a week.

Week later, got a call, took it in, 24 hours later got a call truck is ready.

Very satisfied with my current dealership, even though 2 years ago when I wanted to trade my old 2003 f150 for a used 2011+ truck, they didn't want to work with me. So took it else where, other Ford.

So service department rocks awesome, sales sucks chunks at this dealership lol.

Cost at dealer will be $3200+ .. you could get ESP for 50k at $1500. $3200 Is to start and that's not all the parts, doing in your driveway with many additional parts you can add since your in there $1500 or so and your time.

THIS IS AN IMPORTANT POST, and I will likely start a new thread here shortly. PLEASE READ.

For everyone who is having their timing service done at the dealer or elsewhere, before they put one part in the motor ask to see the parts list.

A potential customer called last night regarding a motor and while discussing the particulars he mentioned he had his dealer perform the typical TSB and he heard a rattle after a couple miles of the work being completed. 500 miles later, both Intake banks were timed horribly, and the motor spun a bearing and popped from the wear particles that the improperly installed timing parts caused.

Ford had the primary tensioner and right hand chain guide arm part numbers wrong across Ford parts and dealers

Since then i am pretty sure that they have made the proper corrections for those part numbers, but please be proactive and check before hand with the dealer or shop.

Incorrect Tensioner pic 1

Pic 2: timing off in that short of time.

Image


Pic 3: what the tensioner and arm should look like. I have posted part numbers of both correct and incorrect tensioners in this thread with images.

Image


I hope this helps save someone a major headache, time, money, and their sanity.

This guy is saying the opposite.
Go to 17:50


He is showing the one on the left in your picture as a the new redesign and the one in the right in your picture is the old style.

I bought part #BL3Z-6L266 A and it looks like the one in the right picture you posted.

The newest TSB calls for BL3Z-6D256-B and says it is a kit but I cannot find a picture of which it is and what is in the Kit.

None of the other TSB's i found even have the tensioner listed.

The new one I bought looks like this
Is this the old or new style?
