Amsoil Ecoboost 70k mile engine taken apart

Shows that while Amsoil is a top notch product you can’t solve a design or materials problem. Bummer for any engine to need major work at 70k miles. But it’s not just Ford - my aunts Subaru died at 80k miles.

I think the best engine in the F-150 is the NA V6. I don’t know if they still offer it but I’d want that engine. I know it has its issues in the SUVs/cars where it’s sideways due to the internal water pump failures but on the F-150 the water pump is external. I suspect those will make it to a million miles most of the time lol.
 
Help me here

Does the 2025 Gen 1-2 not really 3 in my Transit have better phasers or are they all bad?
I have experience with 3 different Gen 1 3.5eb. I traded in the first one with 110k and no issues. The second one is now with my dad and it is just about at 170k with no issues. My 3rd one has 3k so the jury is out on it :)
 
10W-40 synthetic is an antidote to phaser problems. It works by facilitating proper phaser control, preventing wear.
A better solution is to buy a product from another manufacturer, like Honda or Toyota. Also, do you have any evidence… or just throwing out something you believe to be the case about this pig in a poke engine?
 
I drive a 5,300 ford flex with N/A V6. Its fun :)
I get to do Italian tune-up every day.

Edit: I also do my own work on my car so there is no way in hell or heaven or any plane or time of existence would I want to work on a transverse v6 twin turbo engine. Hard pass.
If you are talking about the Transit the EB is not transverse in that application
 
I think the cam phasers in these Ecoboosts must have multiple reasons for failing. I have heard of them failing in as little as 3,000 miles since new. I think it can be an out of tolerance part or installation error due to poor quality control that can lead to infant mortality, or it can be a maintenance related issue when the oil screens become clogged due to sludge or debris over time (which usually leads to them failing over 100,000+ miles).

I am a bit skeptical that oil viscosity is a big player. Consider that the engine needs to actuate the phasers with engine oil on cold starts in outside air temperatures running the gamut from -40 to +120F. At -40 even the 0W-20 is going to be what, 5,000 cSt? These phaser problems seem to manifest on cold starts.

Well, this one was run on maybe the best oil available and was squeaky clean, which probably suggest sludge or debris in clogged screens is not the issue. I agree that viscosity is probably not the issue either, so the 10w40 suggestion is unlikely to work. Poor maintenance never helps… but from the way this reads, this Ecoboost in the early years is engineered wrong and is a ticking time bomb. Usually with threads like this, you’ll get one or two folks saying “my engine is at 300k, has never been opened and runs like a sewing machine,” Where are those folks now?
