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.

You may want to trade in at this point - you will be farther ahead rather than jumping into the moneypit of Eco maintenance and reliability costs.

Anyone having problems with timing chains AFTER the dealer has installed new ones with all new phasers and everything? I'm buying back my 2011 Eco that I traded with 72k. Guy who bought it was local and just traded it back in with 106 on it. Check engine light just came on when I went to the dealer to see it when I found out my old truck was for sale again. I need a truck and I'm able to swing a 3rd vehicle so I really wanted my old truck back when I saw it. Usually wouldn't buy a truck with this high of miles but I know where most the miles came from and I just really miss that truck! Lol.

So dealer looked into check engine light and they said they are replacing all phasers and timing chain under a TSB. Putting in new plugs and wires, fresh oil and filter and a new battery. I'm hoping with the updated timing chain and stuff I shouldn't have any other issues out of this truck. Best part is all this work they are doing isn't costing me a dime!

It will come back. How soon, anyone's guess. Usually when these engines get taken apart, they never go back together well. Remember, if you have the clicking, the cam phaser came apart and chunks are all over internals chewing it up. I would run away from this headache.

Thats all false info. They do not come apart they wear out. I've had absolutely zero debris in my oil before or after having the repair done.

Haven't seen anyone who has had the repair done have the components fail nor an engine failure afterwards.

After talking to Amber and getting approved for a rental vehicle I dropped the truck off. It took days for them to free someone up to start it and listen and sure enough they heard it and recommend replacing everything. It's been three days and after multiple messages left and a couple emails I can't find Amber. I hope she's ok, but I really need some answers as to what direction I can take. As it stands I'm not sure if I'll get it back before the lease is up.

Well just got my 2011 SCREW FX4 back from the dealership where they did 16-0027. During their test drive after the fix they also got the high speed shudder with the misfire code so they replaced my plugs and coils as well. Truck seems to be running fine now. Has 82,000 miles so had to pay 3100$ for two well known issues! Stinks. My third ford truck in a row but been disappointed in the ecoboost.

2013 Ford F-150 with 105,000 miles, just had 16-0027 done by the mechanic got it back occasionally making the same noise on a cold start, took it back they checked oil pressure at idle at the pump 15 PSI the spec is 25 PSI.....now they are debating whether a new engine is needed or to just replace the oil pump....

Replaced the A/C compressor in my truck last year, not impressed.

Maybe some people like their trucks more than you do ya hoop!

In 2013 I bought a beautiful loaded blue super crew FX4 4x4 only to return it after 3 days for a major factory paint flaw and transmission that went into limp mode on the way to the dealer at 500 miles. They were kind enough to offer to repaint and repair it. Instead I dropped a bunch more money on a white platinum Ecoboost. The factory remote start has been intermittent at best (and duplicated by the dealer twice) to this day. They just flat out washed their hands of it and won't bother with it anymore. Now I have been hearing a little rattle at startup for some time and didn't really pay much attention to it. I should have because at about 63k miles this thing sounds like it's gonna come apart at startup, but then again they never repaired the known problem under warranty so who knows. 3k out of warranty on a known problem (they've had the same problem going back 10 years on their cam phasers in V-8's). Ford tells me they'll split the cost on the repair. So I'm going to take the "deal" and move on. You would think that after all the issues I have had to deal with buying their products that they would want to do something better to make it right and keep me as a customer. I have spent quite a bit of time in cheap rentals while I was paying for this fancy ride. Such a shame as I have been just dreaming of the new Raptor. Hopefully whoever I buy the new truck from will back their product and actually do right by their customers. I thank the reps who troll here for trying but I have found you have no power to do anything other then company PR.

Kinda your fault you never paid attention to it. Not theirs. If you didn't bring the rattle to their attn that's on you buddy.

I brought the remote start issue to them for 3 years and it's still not working. The sad part is I've brought up at an oil change that it ran rough in the morning. Know what response I got? That's common to the motor. I guess he wasn't lieing.

I took the time to reread this whole thread and I can't help but notice these poor Ford PR people are pretty much helpless in what they can do for us. I have yet to see anyone say the only reason their truck is repaired is thanks to them. They jump in and give us hope only to be disappointed when we waste our time following their recommendations. At least that's been my experience. How many people have posted the TSB's stating this is an emissions coverage to 80k and not one reply from these people on the issue with any substance. You folks have a tough job. I am sure your heart is in the right place wanting to help but knowing all you really offer is feel good words must suck. I for one am disappointed in the position Ford puts you and the customer in trying to save face and money.

Timing issues directly relate to emissions. Is there anyone in Cali that can take this to ARB and force the issue? Maybe when they get done with VW they will look into this since it seems to be an ongoing issue with phasers across multiple motors.

Well just got my truck back from the dealership yesterday, was in the shop about 4 days, they replaced the timing chain and phaser cams. So far no rattle on start up, performance seems unchanged. Hoping this was a permanent fix for the issue and I wont have to be back in the dealership any time soon!
 
#283 ·
Going on a year since the TSB, no issues at all.

Seems like a lot of motors I see with timing chain issues that I have been sent pictures of or were discussed with me tend to look like this. Probably a large part of people who do not take care of their trucks maintenance.

In defense I do know that some issues happen with people who are anal with OCI and take great care of their trucks. I just think you never really know since we are on the old innerweb

I was speaking to the guys in the service department at one of the largest dealers in NJ and largest selling servicing in country. I know these guys well so they don't BS me. They have performed a total of 15 timing chain TSB, or timing chain replacements since the F150 has had an ecoboost motor in it.

So that's 15 total. Not bad

I get confused when people send pictures of this and say this is normal and they used amsoil every 5,000 miles with the truck at 63,000 miles. I mean come on really




Common sense should be more common
 
#285 ·
Agreed, I have seen a lot of engines as a Tech with Ford and it was always fun when you ask to see the maintenance records and the customer says, "I change my own oil every 3K miles"...
Sorry to tell you but your motor tells me another story...

I have pulled apart phasers from 2013, 2014, and 2016 model years. I found what I believe is the cause. There is zero differences in the phasers unless some hardening or alloy characteristics were changed. They have the same part number as well and engineering numbers. Timing chain will certainly be replaced as and probably some other parts. I will try to take a video of what I found on two of the phasers later today

The new revision phasers were released this year, and I believe will be used in the Gen 2 engines.

I had mine done at 18k miles, with full synthetic used the entire time. I've had 0 issues since the new ones were installed, and I'll be checking them in November when the engine is built.

Same here no issues in the past year since the phasers were changed last September

You should not expect another failure soon, correct? If you do see a failure, it may be another 30k - 40k down the line.

#293 ·
I doubt it'll see one at all.

You won't see it fail again from what I found. Phasers on the 2016 fully updated assembly use the same part number as the 2014. They are fine. I'll take pictures. It casting or some type of debris that gets into them. It is something non magnetic, and only in a few of the passages


Common sense should be more common
 
#295 ·
I'm pretty sure a year or more ago someone who did the job his self out of warranty found that the screens in the oil passages to the phasers were full of casting debris which clogged the oil and thus stopped initial start up oil flow to the phaser.

#296 ·
Here is the same phaser from a 2014. The only difference between these images is that it I moved the internal parts simulating how it moved when the motor is running. You can see when in the first position, it is clean, but when it is in the second position, there is large amounts of particle debris inside the "chambers or galleys"

I believe this is casting debris from new start up on new engine assembly. I also believe there is a lot of burrs on the block, especially on the edges of the cylinder block deck surface.

I should note the particles are non magnetic.

Seems like ford needs to put more time into QA/QC inspection and block prep.

Or, flush the oil system before starting assembly..

rbrown - those pics are a bit fuzzy any chance you could try and re-take a bit more in focus?
for those of us suffering the occasional rattle problem but in the likely spot of having to cover the work (or do the work) ourselves, knowing what we're looking for to confirm diagnosis would be really helpful.
