Just picked truck up from Ford shop. Had latest tsb concerning timing chain (16-0027) done.
$2400! Timing chain guides were not in the tsb but had them replaced. Also new belts, since no extra labor was involved and new plugs and boots, which I was going to do but, mechanic said he'd throw them on.
Cold start rattle started months ago, but didn't throw code til last week, so figured I better get taken care of. Had approx 85000 miles on truck when it started. This is a known issue and Ford should be taking care of it up to 100,000. Even called customer care, told them been driving Ford pick ups for 30 years, have maintenance records, how 'bout a little help....nothing!
Anyways, parts and labor are covered for 2 years, so there's that as consilation.
Anyways, thought I'd share and will post on any issues after this repair!

 

Oh, a couple of more things, the only other issue is the slip/bump on driveshaft. Says it's a two piece drive shaft issue....its not, one piece here.
After a few thousand miles on the oil change Ford did during the tsb, will go back to full synthetic.

 

One piece driveshaft is the one with the slip and bump issue, which is usually fixed by cleaning and lubing where the driveshaft slips onto the transmission output shaft. (Ford has a Motorcraft P/N for this).

 

^x2 sorry I didn't post the link in the other thread, my work computer is weird at what I can and cannot paste on this forum

 

Does any of you know if the rattling on cold start issue will be covered under warranty on my 2011 EcoBoost at 60,085 Miles? Have you guys heard if Ford has any recalls on it? Because they should! It just don’t make any sense to me that Ford will not take ownership of their bad design parts and labor at their cost! Like I never heard of a freaking issue like this in an engine at only 60k miles. I’m the second owner of a 2011 low mileage EcoBoost 3.5L and I just became aware of the rattling noice on cold start 2 weeks ago and went crazy digging in for info. I wish I was a lawyer because I will open a case on this and get your endorsements for Ford Corp to give us all new engines. Any info if the warranty covers this issue being a 2011 with 60,085 Miles or any Recalls on it will be great! Thank you in advance!

 

I guess it depends wether you have extended warranty. Basic powertrain warranty is 5yrs or 60K, whichever comes first.

 

Doubt the timing chain issue will ever be a recall since it's not an actual SAFETY issue.

 

I have a 2011 3.5 Ecoboost. I bought the truck as the second owner with 78,000 miles on it. The timing chain rattling started within 2 weeks of owning the truck. I tried taking back to the dealer and they told me I had to leave it with them until they could hear it. The rattling didn't happen every day, only once in a while. IT appeared to happen more frequently in colder weather and if I let the truck sit for a week or so. I did record the rattling on my phone on 2 different occasions. I dropped my truck off last week to have them do the lead frame and told the service advisor about the rattle. When I showed him the video, he told me "No problem, we can have the timing chain issues replaced under extended warranty", which I have. I only have 200 miles left on my warranty and figured I needed to have this repaired so I am not out with a blown up motor or any other issues. My service advisor just called me and told me the inspector showed up and started the truck and it didn't rattle. Not sure what they are going to do. I called MPP warranty and they told me they aren't doing anything until the inspector gives them his written report. I called the dealer I bought the truck from and they told me they will not do anything to the truck until their technicians hear the noise for themselves. Even if it takes a month or longer at their shop. I call BS on this whole mess. The TSB states that if the owner of the vehicle hears the rattle, it should be repaired by the service dept. The sad part is, one dealer is accepting my video and the other I snot. But neither seem to want to do the repair without their techs hearing the rattling.

 

Just heard from the warranty dept today. They are refusing to cover mine because the inspector they sent out started the truck and the timing chain did not rattle. They don't care about my video proof of it happening. Looks like I am going to have to try and escalate the matter with the dealer. If no acceptable response is given, I may speak to my attorney. Any ideas or thoughts about how to go about getting them to actually abide the extended warranty? MPP is who I have the extended warranty with and the truck is still under warranty with MPP. But only for 200 more miles.

 

Park your truck at the dealership for 2 days, show up on second the minute they open, grab 2 mechanics, take em to your truck and start it. If there's no rattle, then I don't know what your problem is.
Mine would sit overnight, in my driveway, and rattle EVERY morning I started it!

 

I'm willing to bet there is fine print protecting them from providing coverage based on nothing but a video. Videos can be faked.

I think you're effed. Sucks. Aftermarket warranties are a waste of money as they almost never ever pay out unless the engine is actually blown.

 

I'll have to speak to the service advisor that convinced me to leave it with him and he swore everything would be covered, no problem. He had them replace the lead frame due to the transmission shift indicator not working and said no problem, it is covered. Only to find out, he had the service guys replace and repair the trans before he ever called the warranty guys and got approval. MPP warranty is saying they are not covering the trans work because the work was completed prior to them being able to inspect the truck, and that I am on the hook for that bill as well. The service advisor hasn't even contacted me yet to tell me any of this. I found all this information when I called MPP to inquire the status of my truck being in the shop for over a week with no response from anyone. I will be trying the hold the service advisor at his work for the transmission work. Not sure how well that will go over either.

 

I had the same problem

What was your ending result?

 

That's the problem. My truck doesn't do it every morning. It seems to only happen when the temp outside is very cold. It ha happened, when the weather is cold, every morning. As the weather warms, the rattle is gone. It also would do it just prior to on oil change. After oil change, no rattle. It is still at the dealer and they are trying to figure it out. The service manager heard it the other day and he is trying to get it fixed via extended warranty. We will see. Going on 3 weeks at a dealer service dept.

 

DISCLOSURE: I don’t recommend or condone this, but here is a suggestion.

Run a hair thicker winter weight oil. 10w30 if not and it still is a silent ninja with no rhyme or reason to when or why the clacking happens perhaps try a 0W30 or SAE30 oil and it will drainback faster. Thicker winter weight oil will pick up and pressure the motor slower but will also (maybe) drain back slower)

Don’t listen to me. [emoji851]

 

In conclusion, don't even read this post. Lol

Great example/proof. I’ll be surprised if they accept this as grounds for a warranty repair. All depends upon your relationship with the dealership.

 

first rule of aftermarket warranties, never have any work done untill its authorized.


Had an aftermarket warranty for my wheels and tires on my Audi, took into the dealer who point blank told me they wouldnt schedule work on it till an technician inspected it and sent photos to the company for approval. two days later i had a brand new wheel and tire.

your dealership should TOTALLY pay the cost of that transmission repair.

 

Update on the timing chain. I just heard from the dealership. They have been approved to perform the timing chain TSB with all the misc. parts. They will be tearing it down on Monday. The dealership is also trying to get the warranty company to approve a loaner vehicle for me also. As for the lead frame repair, I guess I am on the hook for that, so far. I may try and fight it when they get the timing chain TSB completed.

 

Sorry to guys who PM’d me Info asking about the parts for proper timing chain service. My messages weren’t received

Please email me ryan@rmbmotorworks.com if you would like to know the correct and latest parts list from ford OEM / Motorcraft.

Easier to not miss PM’s with my email.

Please PM me also if you’d like I am updated the list Monday.

 

I am getting ready to do this repair on my own dime. I ran into some issues I am hoping the experts can help on.

1) Tasca parts shows the right chain arm guide as "discontinued". Part number I have is AT4Z-6K255-A. Is this being redesigned? Is there a new part number? Or is Tasca just wrong?

2) It's my understanding if you purchase the water pump assembly, you don't need the water pump gasket and o-ring. Is this correct?

3) What is this auxillary pump? There's two gaskets to choose from depending upon year. Do I need one of these gaskets?

4) I know the crank bolt and the cam bolts both need replacing because they are TTY. I also noticed on FordTechmakuloco's video that the fuel pump bolts are also TTY. Does anyone have the correct part number for these bolts? Are there other TTY bolts that I am unaware of?

5) Finally, when removing the valve cover there are what appears to be rubber seals around the spark plugs and the VCTs? Do these need to be replaced? Do people get vacuum leaks at these locations?

If you can help answer any of these questions I'd be most grateful. Thanks to everyone who has contributed to this monster thread!

 

I highly suggest purchasing the HELM manual, these are common questions answered there and every bolt in the motor is tty

 

Awesome! Thanks. What is your source for the update to the tensioner arm? That part does not come up as F150 for me. Perhaps it's too new and they haven't updated their part numbers. It does show for 3.5L.
Is the arm wider? I was thinking perhaps they made it have a tighter starting position, so when it loosens up it has more travel before it gets all full of slack. Same thing with the tensioner. Does it appear to have more travel than the steel one?

On the Aux Pump re-using the bolts with some thread locker is okay? I was planning it this way but Ryan suggested everything was TTY. I only have 68K on the motor and haven't driven it since I started hearing the rattle, so I am debating if I should change the AUX pump or not. It's digging deeper and another $40. Is there a way to check the slop on that idler gear? I know, I know you're already 2 days into it and out about a grand, so what's another $40? Right?

You've been a great help, I am actually looking forward to the challenge! Installing new parts is always fun.

 

Source is the ford parts guy I used and the fact that that tensioner arm is listed as an alternate to AT4Z-6K255-A on several parts websites. Not sure why ford can't get their distribution chain in order. Arm is basically the same, no more thickness than the old one. The new tensioner also doesn't have more travel. In the end, I don't believe the tensioner is the problem. It is the lack of oil to the phasers that is causing excessive timing chain stretch.

I certainly don't want to argue with what Ryan is saying, but the ford service manual only clearly identifies 8 bolts/nuts as needing to be replaced during this procedure. 2x exhaust phaser bolts, 2x intake phaser bolts, 2x HPFP bolts, harmonic balancer bolt and the nut on the HPFP line (which I didn't replace because that's just crazy. Torque it back to 71 in/lb and call it a day.) Almost every other bolt in the entire process is a torque plus angle bolt, which is different than a torque plus angle to yield bolt. Water pump, chain guides, tensioner, aux pump, front cover bolts, valve covers, manifold, HPFP flare nut etc. etc. are all torque plus angle and are reusable according to the service manual. I wouldn't use any thread locker on any bolt in the engine.

I changed every single timing component listed in the manual. All 4 guides, primary and secondary timing chains and tensioners, VCT solenoids, phasers, idler gear, cam sprocket...everything. Also threw in a new water pump, oil cooler, harmonic balancer and thermostat housing (cause a new one looks pretty). Also my truck is at 98K.

 

I just checked my order over at Autonation white bear lake and it looks like they are substituting the tensioner and the tensioner arm for the new parts you listed. I think the older steel tensioner is being superseded and neither of the older parts will be available once stock runs out. Are the negative comments on the new tensioner in this thread?

 

Post #800.

 

I agree the issue is the phasers not getting the proper oil. Is there some seal inside them that keeps them from bleeding down? Why are they going dry? Was this fixed with the new phaser design? I mean is it as simple as putting a tap on the valve cover and using a small pump to squirt oil on the phasers before startup?? I'll do anything to make sure my grand is well spent. I don't want to see this issue again anytime soon after I repair it. I'll probably just go by the book and drop more coin for the secondary chains, secondary tensioners and aux pump. Was trying to save some money, but it just isn't worth the money to skimp in a situation like this.

So your truck runs much better now? Better than new?

After doing this as a non-pro, I can tell you it is better to do more now than have to go back in there. The truck runs 100% better than it did but I was way out of timing and getting P0016 codes set all the time and the truck basically limped along. It still has 98K on it so it doesn't run like new. Looking at the valves while I was in there, I wish I could have spent the time to clean those as well...pretty coked up. I got over 90K miles before this problem and to be honest I'll be happy with 50K more before I trade it in. The way I look at it, I spent $1400, basically one month's payment on a new platinum truck.

 

Get a nap dude.

 

^^^ WOW!
@rbrown no worries, and sounds good. I'm on this site mostly at work and my work computer hates it as I can hardly quote things or type so wasn't sure it went through. That looks killer, love the told mounted turbos and the red covers make it all pop! Sounds good and get some sleep!
