No more Navistar diesels in HD F's?

Kind of old news. Ford's been developing their own in-house diesel for over a year now, codenamed "Scorpion"

It's 6.7 liters and initial ratings are like 400 HP, 700 TQ, and will supposedly get 2-3 MPG better than the 6.4.

The Replacement?

The agreement to terminate is not old news though . . is it?

MOford21 Jan 16, 2009 05:36 PM

Probably not but it was pretty much going to happen anyway. And yep that link you posted is the replacement.

Thanks for the link though, nice to officially know that Ford has cut their ties with Navistar and can maybe get their diesel engine image back to the days of the 7.3.

Been living under a rock much? There are at least 2 threads that I know of off the top of my head in this forum alone about the new Ford developed engine.

The agreement to terminate the contract has been all but signed for some time now. The only thing that has changed is that they finally put the ink to it. Nothing really new at all.

Yes, you are right about that. I think Ford has lost a lot of their initial advantage in the HD diesel market.

Have you driven a Ford Super Duty...lately?:p I think that Ford still has their edge where it matters most. I think that they have just lost a lot of reliability because of the Navistar engines and they are trying to get that back. I don't know if that is Ford's fault or Navistar's fault. I just hope that Ford does as good of a job as they think they can. Navistar/International is no newcomer in the diesel engine industry. The engines that Navistar has built for Ford over the last several decades have been used in a lot more applications than just Ford trucks. It should be interesting to see how reliable the 6.7l Ford diesel really is.:thumbsup:

With anything new will have lots of bumps the first run out. But eventually
probably be just as reliable as others. The trick will be how bad the
bumps are and keeping customers returning

I agree. And a lot of that "how bad the bumps are" depends upon how well Ford takes care of problems when they arise. I don't care if a vehicle has problems...as long as Ford fixes them in a timely manner and gives me something to drive while they are fixing them.

Well, maybe they'll get it right since the engine will be designed and built by Ford. Although I have had two 7.3L's and four 6.0L's that were all virtually flawless and have no need to complain, I think the big mistake was the International engine and Ford electronics combination. International tested these engines for a long time, and Fords introduction of their electronics and controls seems to be the root of a good portion of the headaches.

If I recall correctly, somebody looked into the Powerstroke series used in International trucks and showed the engine had a far better track record based upon the engine with International specs - not squeezing out the extra hp/tq like Ford did to compete with the other two. Then again, the quantity of diesels in Ford trucks is probably way over what is in commercial rigs, but you see the point.

I am very optimistic. I have had enough diesels that were good engines to NOT be scared of the next engine coming down the run. I'd love a 6.4L, but the fuel mileage and cost of fuel is stupid for my use. Now, when the Baby Stroke hits the F-150, EVERYONE will get in line behind me. I'll test it with no worries. I'm not into the "work out the bugs first" thinking. My 2008 F-150 is supposedly "well tested", and I've had my share of idiotic gremlins that should have been "worked out" by now. On the same note, stuff your hp/tq competition... give me an extremely reliable diesel with excellent fuel economy, and I'll be happy. Unfortunately, I forecast that this EcoBoost will be the top "grunt" engine in the F-150 because it's power does nothing but exceed what we have been doing with the "underpowered" 5.4L for years now. And, out tow numbers keep going up.

you do know that ALL of Ford's diesel engines in the F's have ALWAYS been international/navistar motors. going all the way back to the 6.9...

ManualF150 Jan 25, 2009 03:02 PM

I'm rather disappointed Ford isn't continuing the Navistar line in the diesel sector. If you look at it, I'd rather have a REAL diesel engine in my truck, rather than some fabjob the Ford diesels are.

I don't think the 6.4l is anything like the reputable 7.3l diesel.

I don't see the 6.4l in heavy duty trucks... the only thing I see them in are F-250 to F-550s... and those are just simple light/medium duty pickup trucks. IIRC the 7.3l was used in many applications, like school busses, generators, farm equipment, etc. I don't see the 6.4l being used in any of that.

Yes I do...

You just laid a premium cut 2x4 in front of me and I tripped and fell flat on my face... :lol:

Thanks for teaching me something. :beers:
