You know that's good but
The whole reason the Navistar engine had so many problems was becuse Ford had to have control over the fuel system.
It was screwed up on the 6.0 and I'm not up to date on the 6.4 but I've heard there are problems with that one as well.
There's a old saying
"Those who do not remember the past will relive it."
The main reason there's a V-8 diesel would be
Americas love with the V-8 and the need of a higher revving diesel engine.
Back in the 80's when they started putting diesels in pickup trucks the 3 speed auto was the norm.
You needed an engine with a wider power band. And V-8's could do this and we all loved the V-8
But if look at the larger trucks with diesels
They all went thru the V-8 phase
Now days I know of no V-8 diesels used on the road
They have all gone back to inline 6's
If there coming out with a new Ford diesel
1) They need to fire the guy in charge of the fuel delivery
2) They need to make the new diesel a inline 6 and back it with a 6 or better yet 7 speed automatic.
And if they what to stay in business
They should have 2 new diesels
Both inline 6's one should get good mileage and another bored out or stroked eng. that would cover bragging rights for HP and torque.
And both need to have a perfect launch, and it needs to happen damn quick!!!!!!!!!!!
There losing market share
