2019 Ford F-150 3.5L Ecoboost MAJOR ENGINE FAILURE! Full Teardown W/

Right!
He knows what sells and what makes him money. No sense keeping parts around forever just in case someone in the next 5 years may want to buy it.
 
I have a good friend who works at a local Ford dealer as a service advisor, they replace a LOT of these engines under warranty. With that said, the one in the video was likely tuned and pushed beyond its limits to break a crankshaft.

I'd think tuning would sooner show damage on the piston or the rod well before destroying that massive crank, but I honestly don't know too much about these engines either.

Agree. The rods are fragile if your tuner is stupid, but the crank is good to over 800HP. It had to be scored by debris and then heavily stressed, I would imagine.
 
I don't think that engine got enough oil changes. The bottom of the pistons were filthy. I don't think poor maintenance will snap a crank like that though.

So where can I get pre owned water pumps? Everyone seems to throw them away...
 
If he was pushing 800hp, I want to know what trans was behind it. While I quite like the 2.7 eco in mine and called it one of the best parts of the truck, I’m not convinced of the 10r80. (Sorry @ctechbob, I know you are in there with me).
 
Looks like it was neglected while being worked like a fleet tow vehicle which led to the first timing set going bad, then the rings got sticky from being so dirty, and the crank was probably bad from the factory so a misfire or odd fire hit it just hard enough to go boom.
 
What's sad is that my city is surrounded by a wall of blown up 3.5 Eco's. So many that there isn't room for the 2.7's

I guess Ford must have built 7-maybe 800 million of them by now because they are just that bad.

Is it really that bad? Is this because of the ease of tuning them without building them up, or is there something else? When I was more involved in the RV community, people were quite happy with them in those circles.

I think the thought process on the tuner is that all the soot and carbon have the footprint of being heavily fueled.

Id say no tuner or perhaps a mild tune not enough to snap a crank based on the upper rod bearing shell not being worn on most rods. - when you are really making big power the upper bearing shows it.

5 Star Tuning’s late (sold off) shop truck was making over 720rwhp and they had not touched the trans. Supposedly, it was driven over 60k in that tune before the owner sold it to buy a newer model.
