Default 3.5 eccoboost cam phasor

Doing my homework i am reading that the Ford 3.5 eccoboost are prone to issues with the cam phasors which can lead to some significant repair expenses. Can any of you guys who follow this stuff comment. Is it an infrequent issue? Any maintenance procedures that tend to prevent it?

I scheduled for ford to do it in a few weeks

A lot of the cam phaser, and timing chain problems are a result of lack of maintenance.

Thanks. Was not aware of a recall. Other than that the 3.5 is a keeper?

I have had mine replaced once and they are rattling again. 99,000 miles. Extended warrenty covered it. I recommend no more than 5000 mile oil changes. I ran by the oil life meter.

Ford is having troubles in most of their engines.

Coworker bought a 19 with 15k miles. First day home noticed an engine noise. Returned the truck for a different one and the dealer said that his first truck needed cam phaser work.

This is beginning to sound like the 6.5 GM diesel I owned. Four injector pumps in 127,000 miles.

2015 135k miles and only time I have issues is if I push past 10k on oil changes... Iíll get a code about turbo underboost and cam timing... change oil at 10k run royal purple oil and it hasnít missed a beat.

Fastest, strongest truck Iíve ever owned, including a couple of diesels.

2019 had a new motor @96k, extended warranty repair as a result of timing chain problems. Dealer told me they were doing 3-4/week. New truck arrived and I never got it back from the shop. Was a great truck other than that small issue lol

See Ford TSB 18-2305. This only applies to 2011-2015 but the Ford mechanics tell me the newer trucks are seeing it too. The problem shows itself as a nasty rattling noise for 2-5 seconds at cold start. It's timing chain slap caused by worn/stretched primary timing chain. The early TSB's only replaced the chain but the newer TSB replaces all 4 phasers and all 3 chains. Ford now says it's the phasers causing it. I've done a ton of research.
My 2013 just started doing this after 140k miles. Not every morning but hit and miss. If you let it go it could possibly jump time and throw CEL or worse.
I just ordered all the parts and tools and will be starting the job Monday. My mechanic wants $2400 and ford charges $3k+. Motorcraft parts and special tools about $600. I'd let my mechanic do it but I'm due tires so gotta save somewhere.
As a side note, I maintain the truck religiously with oil changes every 5k with motorcraft filter and synthetic oil, so the idea that it's caused but poor maintenance is hog washbut I'm sure poor maintenance will contribute to an early death. I'm disappointed but I still love the truck and will keep it. It's been a good one.

My 2017 started the timing chain rattle at ~25,000 was at the dealer multiple times and they didnít hear it since it was sporadic. No codes. Dealer finally heard it and replaced the parts. The repair lasted less than one year and it want back in for the same fix. Itís not maintenance related. Itís a bad design/bad parts and common in the 3.5. I got rid of that truck right as the warranty expired and went with the 2020 5.0

Just got rid of a ‘13 with 165k. Started getting noisy at 75k and having issues. That truck left a really bad taste in my mouth. On the plus side I became a much better mechanic as a result of owning it. It would take a lot for me to try their trucks again.

2012 started a slight rattle around 40k by 68k it was easy to tell it was the chain. Dealer could not "reproduce it" till 68k and did not document it right so Ford refused to warranty it. I took a 3k on trade in

2017 timing chain at 30k. Since December this is the longest I have had my truck and im about to hit a month with it

Battery died just under 2 years
Starter died when I went to pick it up for the battery
Timing chain at 30k
2 injectors at 40k
Cats at 40k from injectors
NAV dimming issues that they have now tried to fix 4 or 5 times and still doesnt work correctly
Weird shift problem from 4-5 that causes the truck to fall on its face. I have never been able to reproduce for them.

I think once the extended warranty is done it is gone and im switching. Absolutely love the motor when it is working but it is not worth the headache and being in a loaner for months at a time.

That and the fact it would currently cost 20k more for my exact same truck right now with the same possiblity of all the headaches ill pass


Then on the other hand a friend has 2011 with over 150k and has had no issues.

Sounds like the remedy is to replace parts with the same parts. No one and done solution. No magic bullet.

I had a 2012 that had 220,000 when I got rid of it. I had the rattle one time and threw a code. I always ran synthetic oil but started getting my oil changed at one of the chain stores. I think they must have put cheap oil in it because once I went back to doing it myself with full synthetic I never had that issue again. Only other problem I had through the years was it ate plugs pretty often and I never figured out why because they were easy enough to change. I have a 2019 right now so far so good.

Have a 2018 w/ 35K miles and no issues at all in regards to the cam phasers or rattling. Change the oil every 5K miles. Seems to be hit and miss reading the posts and hopefully I don't run into issues. I like the truck but will probably go with a V-8 if I do trade it in.

Heck you can't hardly find the v8. I'd say 70% of the available trucks have the 2.7.

I have 2014 and it has done the rattle for several years. It has 120k miles and I have hardly changed the oil in mine let alone any other maintenance... so yeah, mine is probably maintenance related but I am going to drive it till the wheels fall off.

I started looking for a 2021 5.0. When I found that this is the first year Ford has gone to dropping out four cylinders when running under light load I dropped that hunt. I would consider a 2020 5.0.

I'm looking at Powerboosts right now. The problem is that it uses the same 3.5 that the Ecoboost uses.

I bought a 2017 with 37,000 on it and drove the truck for 3 days before the endless trips to the Ford house started because of all the phaser and timing issues. They could never get it corrected and I eventually had the dealership where I bought it refund my money and take the truck back. Have a friend who has had his 2019 in 3 times for the same issues.

Loved the speed and the truck overall but the continual issues with that engine have left me never wanting to buy another Ford again. My wife wants an expedition but considering it uses the same 3.5 I wont consider buying it.

I bought a 2012 3.5 new and took it to a 100,000. All it needed was a catalytic converter. I bought my dad's 2013 and it now has 83,000 with just small things needed. I'd buy one again.

I've got 175,000 miles on my 2012 eco that I bought new. Nothing major other than normal stuff.
Truck is not babied.

Regarding the "rattle" it showed up at 160,000 miles. If you turn the key halfway, wait 3 or 4 seconds and let the oil pump pressurize the rattle doesn't happen. I was told this by a mechanic and it hasn't rattled since.
I've also seen on YouTube that adding some Lucas oil additive will stop it as well. The rattle- Is Not a big deal IMO.

Buying another another Eco this year at some point.

They say it will throw a code or go into limp mode, eventually. I've experienced no such issues.

I just know how pricey this repair is going to be and every time it makes that noise, I just put it off another day. Here I am, 5+ years down the road and it is still doing it.

You may want to consult that mechanic with a grain of salt.....the oil pump in your engine is mechanical and doesn't provide pressure until the engine is turned over.

There's no recall for that.....Maybe he's referring to a TSB, but the only one I could find concerning 2019 vct's was for the 5.0.

I'm probably wrong on it being the oil pump. I cant remember specifics.
The point is, give the engine a few seconds to go through its start up sequence and allow the oil to get where it needs to. On a cold start if I wait no noise, if I turnover immediately it'll grind.

Interesting. Sounds like the only thing that could do that may be the phaser control solenoids needing time to open up. One may be sticking causing the phaser to rattle.

There’s generally an easy way to disable that feature. A custom tune can all be certainly accomplish this.

I know in my 2014 Ram, all I have to do is put the transmission in manual mode and select 8th gear. It still acts like a normal 8 speed auto without me having to manually shift gears.

Look into it. I wouldn’t let that 8/4 feature dissuade me from buying on if there’s an easy workaround.
