Ford's new engine...6.7ltr

[Curious Dave]

Interesting.... Some of the feedback was interesting also. But K.I.S.S. still seems to be the reigning philosphy for me. I also like being able to work on my own stuff and not have to call NASA for parts or explanations. Function, reliability, ease of access, plentiful parts, simplicity = CUMMINS.

I have to agree with that. I would never use that name again because in my mind, it's still a PowerJoke.

Aluminum heads, wimpy connecting rods, urea, and up to five injections per cycle, i don't think i'd touch it with a ten foot pole.

And to top it all off they used the power stroke name, i agree with grizzly and AMink, that is a big mistake.

I'll keep my 5.9l cummins with a manual transmission (you can't even get a manual with this new p.o.s. powerjoke!).

Keep It Simple Stupid. My $0.02

While I applaud the placement of the exhaust valves on the inboard side in order to reduce manifold bends, I just don't like it from a maintenance perspective.

Personally, I think the only "proper" turbo arrangement for a vee engine is with each turbo fed from one bank.

I hate to be a naysayer, but that thing looks like a nightmare.

I-6 for me all the way, even if Cummins made a V-8 Diesel I would still prefer an I-6.

I remember in 2003 before it was released, the 6.0L was named one of the best diesel engines in the world; I believe Motor Trend bestowed the title upon it. HA!

While Im in no way a Ford fan, what exactly are the issues with the 6.4? By all reports, its been a fairly good platform. And we all know it will flat make some power...just wondering. Because I havent heard of many myself

It's about time they got a HPCR. Now maybe they can keep up with Dodge and Chevy at the track and on the dyno. Reliability might be another issue though!!!

The title is not based on fact, but on advertising dollars in the magazine which is a common practice for glossy magazines using a re-written press release from the advertiser. Dirty little secret... some articles in the glossy magazines are reviewed and edited by the advertiser before it is allowed to be printed.

IMO, there are several advantages to this design. A couple that come to mind:
Exhaust heat rises for a very short, direct trip up to turbo/turbos.Quick spool, very little heat loss.
Compactness/versatility. W/O the exh. manifolds/pipes on each side of the engine, it allows for a much narrower engine pkge. Very important for use in smaller trucks or cars. Especially for V-8/V-6 front wheel drive applications.
As for maintenance regarding the new turbo location? I can't see any big disadvantages, but I'd just have to wait and see on that. As for all the engine clutter, pulleys, etc? I can see the cab lifted off the frame a lot!
As a side note. IMO, turbos on ea. side of a gasoline V-8 works great, but can be very cumbersome. My thinking is, as this new design evolves, I would not be surprised to see it also tried on gasoline fueled V-8/V6 platforms also.
For diesel engines, if I'm going to have two turbos, there will be one turbo blowing into the other. Thats the big advantage for our trucks, with the in line six.
I never liked the way they plumbed the exh. pipes to the turbo, on any of the V-8 diesels. The turbos are way too far away from the heat source.

From what I have seen first-hand and from what i've heard from owners... It hasn't been pretty.
Most of the new 6.4l i've seen around here are actually used every day. Being loaded to near max gvw from day one. I talked with one of my customer techs. awhile back that got a new service truck (09 F-350 6.4l) He picked it up in the Dallas area with the service bed and crane already installed. He left Dallas headed back to East Texas and the engine threw the rods out of the oil pan about an hour later.
Another customer that had one in a service truck left it idling while he used his crane for approx. 45 minutes.... It ended up costing them a set of injectors, both turbos, and a particulate filter. All of which the dealer did NOT want to warranty due to "excessive idling!!!".. THis truck had approx. 10k miles on it, I personally think that the bickering back and forth between Ford and Navistar caused many Powerstroke owners to eat repair bills that SHOULD have been warranty by either Ford or Navistar.
Not to mention that they had to pull the cab off the truck to make the repairs!!.
The engine (6.4l) may do just fine in an application where its not stressed routinely. The occasional golf cart trailer, or a boat may be what the 6.4l is better suited for. But, here in Texas, most of the trucks work for a living. Its not un-common to see a 3/4 ton pulling 30K lbs. Excuses like you cant idle a diesel engine without voiding your warranty just won't fly.

[HBarlow]

The same was true of the sick ohh. It was a good engine if the owner drove it for basic transportation as a commuter truck. It was okay, not great. If the truck was expected to pull or haul a load in commercial service is was and is guaranteed to fail.

IIRC, the 6.4L is HPCR. The 7.3 Powerstroke is common rail, just not high pressure common rail. In fact, common rail fuel systems have been in use for over 50 years by Cummins and Detroit Diesel.

My brother has a '08 F250 with the 6.4L and it's never been back to the shop since he bought it. He uses it as a farm truck hauling round hay bales, towing a livestock gooseneck trailer, moving large farm implements to different leased farms, and going to town for parts and supplies. He says it likes fuel much more than his old 7.3 Powerstroke it replaced with nearly 300K miles on it.

Right on, Bill. Most people don't realize that fact about Detroit and Cummins. Detroit Diesel had an almost bullet-proof fuel delivery system in the 2-strokes and carried a lot of the design over into the 50 and 60 series. Low cost rocker arm activated injectors, fuel delivery and return rails built into the head and a $50.00 gear pump for pressure. All you had to do was set the rack correctly the FIRST TIME.
