I have 186,769 miles on my 2011 f 150 3.5 eco boost and I have never had any problems always changed oil at 2,500 miles and have only ran full synthetic mobile one oil I have 0 cam phaser issues no rattles the one thing I have had is where the resonator is on the exhaust the final welds are rusting out and started throwing codes. I couldn't for the life of me find the problem till I got under the truck to change out the o2 sensors as I was getting lean bank 2 condition and low boost condition. When I got under the truck, I was almost done with the o2 sensors and I looked over and seen black smut in two spots and sure enough I had my dad crank her up and I could feel the exhaust coming out the resonator, grabbed some high temp jb weld made for exhaust and no more problems. I can't believe as long as I have had my truck 0 issues but this little problem other than maintaining the truck spark plugs, oil, etc. etc. This has been a wonderful experience and this year Ill be buying another brand new eco boost 3.5 v6 twin turbo.
I see your replacing all the right parts, and you went with oem stuff👍🏻. You did your homework on this motor refresh! Make sure to keep using motorcraft oil and filter too
Ok.. I was gonna give you shit for not replacing the one time use crankshaft bolt but then I saw where you applied the TA-357. You put it on the beveled area of the cover and not on the machined area. Nicely done!
Honestly I regret not replacing, but the engine only had 70k miles on it. I think catch cans are a good idea but I don’t think they are necessary if you run a stock engine.
About to do my 2013 timing chains on my ecoboost. All i need is the 4 sprockets, bolts, and timing chain, and tensioner? I would like to save some money and not buy all brand new rails and tensioners and things like that. Thanks
Great 👍 review and information ! I own a 2016 F150 with the 5.0 V8 , this motor has been reliable so far I am curious about how reliable are the turbocharged Ford engines ? I am lol old school that's why I didn't go for the ecoboost engines.
As with most things, I think a lot of it has to do with how well you take care of the motor. There are definitely more things that can break on the ecoboost (e.g. turbochargers) but I think that is just a trade off to getting all the power that it has to offer.
I have a 2020 Transit 350 with the 3.5 Ecoboost and has 263,000 miles on it with no major issues. I recently replace the charcoal canister vent valve assembly and PCV hose sensor under hood. Mine is the long, tall model. I run interstates expediting with it. It weighs 7,200 pounds with me and my gear in it, and I get between 15 to 21 miles per gallon depending where I'm at , loaded weight, and headwinds. I use Mobile 1 full synthetic motor oil that is the 20,000 mile protection blend, but I change the oil at the recommended intervals of 10,000 miles.
2014 with 130,000 miles. Ive changed the vac pump and both valve covers. Im wanting to clean my valves. I noticed you put the intake on last. So is taking the intake off fairly easy to access the valves? What about walnut blasting them? I cant find anyone around here that does that.
Yes the intake is relatively easy to take off. I didn’t walnut blast just because I don’t know where i would find someone who does that. Cleaning them the way I did seemed to work great.
I looked a picture of the ford transit 250 and found out I have a eco boost 3.5 I knew it had power but that a suprised is it cost a lot more fir that engine.
@@mischiefmotorworks How do you organize all the various fasteners when you remove them? I have yet to come up with a way to keep track of what bolt came out of what hole.
Just buy a massive package of ziploc bags and as soon as the bolts comes out of the hole put it in a bag and label what the bolt holds in place or where it goes. It may take some extra time to label everything but it’s well worth it when you go to put stuff back together.

They are great! I have since bought another one and so far no issues with that one. If they are maintained properly they will last.

Nice job but why not replace the water pump while you are at it? Also what you think about catch cans? Are they worth it?
Honestly I regret not replacing, but the engine only had 70k miles on it. I think catch cans are a good idea but I don’t think they are necessary if you run a stock engine.

Those motors are $$$$. And rough to work on! I was looking to fix up a 2012 ford. Nope too much $$$$. For the motor with high miles and not turbos...
Is it almost always preferable to buy a lightly used OEM built motor, address shortcoming, and install Vs. Buying an off the shelf rebuilt motor?
I just bought a OEM motor so that it would be an easy drop in replacement.

Great job and great video
Thanks!
I’ll probably rebuild my 2.7 EcoBoost when it goes, but I don’t think it will go anytime soon! lol
Very impressive man
Thanks!
Why not replace the water pump?
Probably should have.
I looked a picture of the ford transit 250 and found out I have a eco boost 3.5 I knew it had power but that a suprised is it cost a lot more fir that engine.
Would it be worth looking at the intake valves for sludge build up before installing?
Yes it would! At the end of the video if you skip to it I clean the carbon off the intake valves.

Care to share price of used engine and timing components?
Engine was 5k and an additional 1200-1300 in parts.
For comparison, I was quoted $20200 Canadian ($14700US) last week to have a new engine assembly installed.
Remarkable
Thank you!
Hey mine with 164k miles looks like that inside
That’s great!
