6.7 -Doomed to Fail - Insufficent Testing?

When the oil pressure went away, I shut it off, took off the brush hog and towed it back to the front. 1 piston 1 sleeve rings rod bearings gaskets. Other than that it is original. The steering and hydro lift are going out, I am about to do both of those. Not bad for 70 years of heavy usage.

Really?

So is Ford proud of the fact that they have tested their new motor for fewer miles than the competitions' basic overhaul interval (300,000)?

And does Ford realize that 250,000 simulated miles on a dyno are a lot different than 250,000 miles in the field, overloaded on the road, idling in winter and then run flat out for hours on end. I hear a lot of reports about these trucks being spotted "undergoing testing" - but it never sounds like the truck is under much of a test.

One press release stated that the motor had been teted "for hours on end" - really? This suggests that they think the product is a commuter vehicle and that somehow subjecting it to a full workday is a "test."

Has Ford finally built the ultimate suburban poser truck - ready for a level-kit and fake bead locks?

I know, I know, some loyalist drunk on Kool-Aid is going to chime in here and say what a great job is Ford is doing and Ford can do no wrong. But think about it.

Ford has never manufactured a heavy duty diesel motor before and if the press statements are accurate, the 6.7 has not been sufficently tested-by the company. 250,000 mies? As a test threashold? Are they kidding?

Don't get me wrong- I wanted an excuse to stay loyal to Ford. But if you combine "ugly" with "untested" what do you get?

Personally, If I needed a new truck in the next model year, I get a huge incentive to migrate to the Cummins powertrain... Why take the risk? And while I really like my 2007 F350, it is not like the build quality is much to write home about... The truck has excellent load carrying capacity and it runs away with 25,000 gross. But... Next truck, do I want to do Ford's product testing for them?

The factory gooseneck hitch is a pretty sweet addition.

I thought I read someplace that Florida Power and Light are running this engine in some of their trucks for real world testing?
I for one hope this works for ford as in 2013 I will be looking for my next truck to tow a large 5th wheel camper and if Ford can't get it done I will get a International. Yea I like international and have seen how they are working hard to stay in the game. Remember they are the only engine makers that don't need the Urea(read cow pee) tank. I really want to drive something that uses cow pee to clean up the exhaust.
