Other boards trashing the 6.7

[MCummings]

I have enjoyed for a long time seeing the Cummins on top of the reliability heap (IMO).

It's still on the top, just not so far ahead of the other heaps. :-laf

The 6. 7 is the best engine out there for the new engines and the best are always scrutinized by the competition that being said, I would rather have a 5. 9 with the shorter stroke and less EPA crap in my C&C but was not available in the new C&C frame.



The Ford 6. ohno had massive issues and the 6. four-now seems to be following the same path just read there web sites and per there conversations the 6. 4 is the worst engine of the current big three in problems and MPG and capability not to mention advertised HP.



the D/A is always changing every model year so how can you tell if it is what it says it is. The 05 LLY my company gave me to drive ran hot all the time and that was normal for that MY and is why there is a kit to beef up the cooling system. Just think about it, pay 40K for a truck you cant tow to its GCVWR because it will over heat. The LBZ engines had major glow plug issues and destroyed a lot of aluminum heads and iron blocks (I still don't understand why aluminum heads on a diesel) and the new LMM is having issues like the CTD.



The bottom line is the 6. 7 engine is great, the LMM is OK, and the 6. four-now is still having oil leaks, programing issues (non DPF related) & turbo's failing. The problems for the GM and CTD are related to the DPF, Fords still has poor reliability issues.

Guys I can honestly say I think the trouble with the 6. 7 was a 07. 5 issue not the whole dodge line up I just bought a 08 2500 3 weeks ago and love it the exhaust brake works awesome Haven't towed heavy with it yet but did have a 18 ft trailer with my other street toy on it and didn't even feel it . I have had no problem's what so ever nor do I think I will have any problem's I feel that dodge did there home work and sat down and fixed the problem's they were having with the dpf software and got things back in order . If I had to do this all over again I would not think twice on getting the 6. 7 engine .

 

[RVTRKN]

The C&C has no issues with the DPF except for the MPG loss due to the restriction on the exhaust, I believe it is due to the larger DPF they have over the standard pickup and makes sense due to more volume & less restriction that can burn off soot. The less HP has something to do with it as well, even though I miss the HP, I know it is an extremely strong engine and was the perfect choice in my new service truck for the company I started.



I test drove the ford 6. four-now with the auto in a F350 and was shocked that the HP advertised wasn't even close, the poor performance was evident and only if you were a 6. ohno fan would think it was stronger because the 6. ohno was a poor performer as well.



I could go on about the other makes but people believe what they want to and you will never change their minds, I would just consider the source and leave it at that, we know the CTD is much better than the competition and its just their loss.

As stated above, There's always going to be a certain amount of brand loyalty. I have notice that folks on other sites tend to jump all over a newby if they post about some horiffic problem. Whereas we will give a newby the benefit of the doubt and try to help him out.

Ford apparently has their own issues w/ the DPF. There is a recent posting on the Ford site about an owner's truck going into limp mode when a sensor detected excess hydrocarbons in DPF, which could only get in there from a leaking injector or oil from a another source. Excess hydrocarbons could catch fire and cause the "flamethrower" affect that some on that site have posted about. The truck would not start till the temps drop to acceptable levels. They even have a warning from the moderator that no new postings of the "flamethower" video will be permitted.

Oh jees! Now look what we've done. Now someone on the Ford site is going to post about the meanies over at TDR bashing the 6. 4. :-laf



I will say that there is one thing that Ford and Chevy has that Dodge doesn't... ..... A Crewcab w/ an 8' bed! Sigh... . maybe in '09.

 

[DCreed]

I would like to see the Cummins from the factory with the power and performance the motor is capable of ! Dodge released the HP/TQ info so early the general had time to best it. #@$%! Now ,AGAIN, we have to wait for the inevitable reliability issues to prove who's really top dog. I dont think its too much to ask of Dodge however, to up the stakes and add 25hp and 50lbft to the 6. 7 just to SHUT THOSE GUYS UP !:-laf

The duramax is a stout rig, I wouldn't even put them in the same league as ford. My duramax was great.

 

[EB]

Wonder where EB is, he should be coming up on 85,000 miles by now! Be nice to see another update from him.

Well, I'm not quite that far along yet. I'm right at 80k, should make it to 100k by the end of the year. The truck will be a yr old on the 21st of Nov. I've had one period of trouble and that was a throttle control valve. I had one dealer that I think was guessing at the trouble and put a flash on it that was wrong. It wiped out everything, even the key code. It took another tech at another dealer and it took several days and a lot of calls to star to get everything right again. That was at 50k miles, since then everything has been fine, no problems at all. The throttle control valve was an intermittent problem that finally set a hard code, it was replaced and all is well again.



As a point of information, south Texas still does not have ULSD in every fuel stop by any means. Once you get much past Houston to the south, it might be hard to find.

hmmm... new technology that isn't absolutely flawless? Who'd a thunk? I do seem to recall hearing that the new Cummins already meets the 2010 emission standards... don't recall hearing that about the rest of the crowd... so all we should see are more and more refinements to the 6. 7, rather than another big change... that other engines may be in for to meet the standard.

They are far better than Ford, but stout rig, I respectfully disagree. Maybe in the 2WD but that independent front suspension 4X4 is weak and the D/A fans will admit it, but only to a fellow GM fan. The aluminum heads also adds a weak link in the armor and is the reason they added extra head bolts when they went to the LBZ. The LLY 5spd I had to drive for 22K miles before I got my contractors license and started my own business, was horrible on MPG and was told it was normal when I complained to the service manager. It ran hot all the time and the "torque management" when trying to pass would go into limp mode to save the Allison from the high torque, I thought the Allison was a strong trany?The D/A is better than Ford, but I would never buy one unless D/C stop building theres with the Cummins and started using the International Diesel (PS)



FWIW, Dodge almost went with the International until Cummins took the bull by the horn and paid for the development in a bid to convince Dodge the CTD would be the better choice. After all the CTD 'B' engine was originally set to pull 60K GCVW, that is why they last a long time and are still worth lots of cash even with 200K+

And they're worried about the CTD DPF?... ... ... ... ... .....

RVTRKN... . I will respectfully disagree with you on the 4x4 thing. The duramax had an awesome year sled pulling in the street class. Matt cooper (nwpadmax), tony burkhard Tomac just to name a couple. Their IFS trucks dominated some pretty strong competion all year long. Matt didn't break a single part on his truck all year long up until the very last non-points pull. And it was a rear... go figure? Now that being said... I drive a cummins. I don't sled pull with my daily driver and I picked the dodge cummins for a reason... overall longevity. So do I really disagree with you? Yes and no. Your points are all well taken.

Like I said before, the D/A fans will not admit the IFS is weak unless your talking to another D/A fan. You just need to go to TDP forums to see the complaints on the IFS and as far as disagreeing, I guess we will just have to agree to disagree :-laf

I can stick my finger into my exhaust at anytime and come out with a finger I can eat with. That means a lot to my children and me. I love my 6. 7L. I still have low milage but most of the 6500 miles has been towing heavy in rough terrain. I still plan to do all I can do to improve the air flow from the air filter to the exhaust tip. Improved spray/flow injectors, cool air intake, better intercooler and improved exhaust. All these things should not clog DPF. Programmers are another animal. That may come much later after all the smoke and mirrors clears up.



My 6. 7L has been great. :-laf

With the new emissions requirements it may not be so easy to turn up the power. I'm sure they have a little in reserve for marketing later models, but it may not be as much as we would like.

No Power stroke in the f650 and f750

Not that I'm biased, but I'm guessing there's a reason that Ford doesn't offer a powerstroke in there larger trucks (650's and 750's). What superior motor would you guess they offer? That's right, the 6. 7L Cummins or a 7. 2L I-6 Caterpillar. Nuf said?

EXACTLY!!!!:-laf There was a guy that came in here to work on Thursday to give us OSHA traning and he had a 07 POS "I" mean PSD 6. 0 with banks dual exhaust and Banks intake, bla, bla... He was braggin how fast it was and how much tq it had and I told him I'd bring a real diesel in next Thursday for him to check out... He said well see. Loaded the Beta SMARTY yesturday.
