FYI - I am a fleet manager for an agricultural company here in Ontario Canada. I have a fleet of 126 trucks, which includes 57 F-150's reg-cab 2wd ecoboosts (2011-2013's).

I am a huge Ford supporter and have been very "pro-ecoboost" since it's launch in the F-150. I also own a 2011 FX4 crewcab that has been 5-Star tuned for abour 20,000km's and now SSI tuned for the past 10,000km's.

I am starting to become very concerned with this engine and specifically the timing chains. In the past 4 months I have had 17 timing chains break on 2011 ecoboosts. All trucks were between 130,000 and 160,000km's. Some of them only needed a timing chain replacement and others need a whole new engine (which is over $13,000 Canadian). I am still working with my Ford rep to see if they will help me out with some of them......but it's not looking good because they are slightly past my goodwill warranty (130,000km).

The interesting thing is........the replacement timing chain is thicker and more stout than the original. This tells me that Ford knows they have a problem!

I am becoming very disapointed in the performance of these trucks and loosing confidence in their reliability in my fleet. So far the following issues with these 2011 ecoboosts (outside of the usual ball joints, brakes and regular maintenance) have been very costly for us......

Rear differentials - almost every truck
wheel bearings - most of them
left side turbos - 3 trucks
vacuum pumps, master cylinder - 15-20 trucks
timing chains - 17 trucks and counting (all within recent 4 months)

I am not bashing Ford (yet).......just sharing some real world info with you guys since I have so many of these trucks in a heavy service fleet environment. I even have 6 of them with well over 200,000 km.

Am I concerned about timing chains/engines on these 2011 ecoboosts?......You bet I am. I am even more worried about my own truck since it is tuned and I drive it pretty hard on occasion.......will the timing chain break even earlier.??? I don't know, but I am worried that it will. If I am going to keep it past 100,000km, I will be looking to add an aftermarket extended warranty.

My intention is not to **** anybody off with this post.......I am just giving you guys a heads-up, especially if you are nearing 130,000km's or 80,000 miles on your 2011's.
thinking about it... its likely this thread isn't specific to ecoboost, but perhaps the application of an F150.

as I had aforementioned, I'd saying timing chains usually go do to either poor design causing poor lubrication and premature wear or lack of maintenance.

however 100% of diffs and so many wheel bearings going to me, indicates that these trucks are being used for capacities beyond its rating.

A F150 8.8 is more than capable to be a work truck, let alone an open w/ electric locker 9.75.

I'm thinking that these trucks must be used to haul (not tow) a significant amount of weight, through interesting conditions, likely requiring higher payload ratings and Axels that should be free floading (w/ more bearings). So if your crew is bombing around a heavy load on an engine that hasn't even warmed up... you're going to have issues.


I know this doesn't account for the timing chain issue, but I'm thinking that your guys could have put some main bearing damage on these blocks as well as the transmission and possibly the front IFS setup.

A 250 ton just has so much more of that "work" application from suspension, brakes, solid front axles and free floating rear, that it may be more relevant to your company's field of work.

if what you say is true, that there are changes to the actual timing chain from 2011+, I'm happying I have a 2014 lol

Bringing this one back to the top... On-going thread also here:

http://www.f150forum.com/f70/2011-ec...04007/index35/

Did we ever get an update on the OP's fleet of ecoboosts was doing?

There are many 2011 3.5L trucks coming down with this issue. Mine included. Not necessarily an outright broken timing chain, but it's stretched and going to fail eventually.

Difference in the 2 motors is the HPFP mounted on the Cam. Problem is HPFP, no brainer. Leaking gasoline on the trucks with the problems ?

F150 3.5 Liter EcoBoost ISSUES
Just my experiences with my EcoBoost, not bashing Ford and deffinatly not bashing the Cox Motors that are stuck trying to figure out what Ford Engineers cant.
At 78k miles here are the issues I have had with my Ecoboost:

1. Intercooler (CAC) moisture, truck stumbles on hard acceleration. Somewhat repaired, band aid was re-flash PCM and prevent air flow thru CAC so as not to cool the air as much (condensation averted). Isnt the purpose of the CAC to provide cold air to the engine?

2. Truck continues to stumble and now throws a P0306 (misfire #2) code. Cracked coil assembly. Coil replaced, my dime.

3. Truck continues to stumble under a load and throws several misfire codes at 45k miles. This goes on for SEVERAL months. Carbon arcing on 4 of 6 spark plugs. My Dime.


4. After purchase, started noticing a particular noise. I was told that all EcoBoost do it and its normal. At approx 73k miles, brakes have no assist for much longer at start up. Electric motor driving vacuum pump is the culprit. MANY other EcoBoost are doing this. Easy change, I replaced it myself but the Vacuum pump is $600, my dime cus ALL EcoBoost do this.


5. At 78k miles and start experiencing loss of power, no pattern but I do notice turbos aren’t spooling up. Eventually it throws a P0016 code which relates to crank and cam timing issues. Local dealer says everything is within spec and will contact Ford Engineers for probable course of action. Ford Engineers say….. Check oil psi, scope timing chain, disassemble front of engine. Once accessible, inspect timing chain, phasers (one on the front of each cam that controls timing), phase solenoids (one for each phaser), and oil passages for obstructions. Other than the timing chain and the oil passages, no clue what they are inspecting for and ford engineers are NOT 100% positive that any of this will fix it, they are throwing darts at my dime AGAIN.
Oil psi check ~$75 (labor)
Scope Timing Chain ~$75 (labor)
Access to inspect Timing chain and phasers ~$1200 (labor) Front of engine has to come off (timing chain cover)
Possible parts:
Timing chain with slides ~$140
Phasers ~$150 each x 4 cus they have no idea
Phase solenoids ~$150 each x 4 cus they have no idea
Assorted seals and gaskets ~$?? Unknown.

6. The advertised 22 MPG… Horse hockey.. I reliably got 15 MPG unless I was doing 50 mph then, I could get 18-19. Comparatively speaking, the loaner I got is a 2012 F150 that has a 5.0 liter in it and is an XLT, same route to work.. same person driving, same driving habits and its getting 18.2 mpg. So much for the ECOBOOST being ECO friendly.

7. Newly discovered EcoBoost issues that I have yet to experience.
That black sooty exhaust that is “NORMAL” is causing a build up on the valve stems. Ford has no way of cleaning due to high temps of exhaust gasses melting seals in the turbos, and performance WILL suffer.
Many rear ends having issues with the pinion shaft bearings

As of 10-3
I decided that since I am paying for it and I only want to pay for the labor once, they are changing the Primary and both secondary timing chains and tensioners, all 4 VCT's, and all 4 solenoids. Funny thing was when I was talking to them about the cost of the parts, my dealer had marked up the parts 110% over cost. I googled one of the part numbers and found the part for half of their cost and told them that I will order all parts and provide them with the parts. They have since decided to only mark up the parts 10% above their cost .
The dealer nor Ford are stepping to the plate to help out with this.
Timing Chain is on national back order. Truck has been in the shop now for 3 weeks now. Good times right?

It's very well documented on the forum that the problem is not the VCT's or solenoids. I could be wrong, but I believe there are only two, one for each intake cam. The exhaust cam is slave driven off the intake so it doesn't need one. If you are buying 4, then you really are getting ripped off.

THANK YOU FORD FOR STEPPING UP AND HELPING!!!!!!!!!!!

If you're having so many issues, why not trade it? Stick the dealer with the repair bill.
