Other boards trashing the 6.7

[QWaller]

Lurking some other boards and the buzz is how bad the 6. 7 is turning out (primarily the trouble with the DPF). Something about the regen being passive or something along those lines. Hope Chrysler gets it figured out. It feels odd having the Cummins under scrutiny from the Ford bunch.

 

[FordCummins]

Lets face it, the 6. 4L that Ford runs is no prize either.....

 

[CHolman]

Well we may DPF issues or what ever, but who has DPF issue's and flammes shooting out the tail pipes?... . All new "1st" year productions will have teething pains... . THey have to room what so ever to talk. Then again some of those guys are dumb enough to buy the 6. 0's time and time again, so you have to consider the source. They just have to make themselves feel better about their POS's...

... ... ..... and it also feels odd having the 6. 7L under scrutiny from fellow TDR members from the 1st GEN, 2nd GEN 12V, 2nd GEN 24V, and 305/555 and 325/610 HPCR camps as well.



All I suspect is more #ad
and I'll bet this thread goes no where fast. If there were as many 6. 7L's "faulty" as talked about, there'd be none on the roads.

In any case, I hope they get it all figured out. I want one.

6.7

well Ide say the one's talkin the smack are just Little boy's crying cause they dont have anything better to do yes there was some problem's with the dpf when the 6. 7 came out but no where near what the Crappy 6. 0 and 6. 4 trash thats under the hood of the Ford's I Presonally thing the 6. 7 Rocks I just bought a 08 and love it no problem's what's so ever . I say let the cry babies cry and the rest of us that know better will just keep on driving :-laf

 

[RDHamill]

makes me wonder who is posting the comments about the DPF being trouble. I notice very few comments like that on the TDR.

Mine has been fine so far (knock on wood)

All a person has to do is look at this forum on the first 3 pages. One should be able to find something quickly about some of the new 6. 7 shortcummins being experienced by SOME owners. Obviously not all owners are going to have the same problem. I did not realize that the TDR only spoke of positive experiences with the Dodge/Cummins combo. Not much to be gained by not looking at problems is there?

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

I hit 42k this week, and so far so good. I've had a 05 5. 9 with the 6 speed man. Made it to 277k before it took a crap but I drove the #%$* out of it. The 6. 7 with the auto is a dream, they all have problems here and there. But the Dodge seems to do the best. Still have a powerstoke in the driveway if anyone is looking... .

 

[Forrest Nearing]

all the big three are having teeth cutting issues w/ the new emissions, DPF's, etc.

What's the difference between passive and active regen?

 

[QWaller]

Heck I don't know. I was just making conversation on the board same as I would in person. I don't like being on the receiving end of the truck engine jokes like the Ford and Chevy guys were for so long. Only problem here is: Some of you guys are way too sensitive about your vehicles, and pretending that problem don't exist is exactly what the Ford camp has done for so long with the 6. 0 motor.

What's the difference between passive and active regen?

Short version: Regeneration is the process of chemically changing particulate matter (soot ... which has been trapped by the DPF) into more-acceptable exhaust products.



The process requires a certain heat level.



"Passive Regeneration" takes place as a matter of course, unrecognized by the driver, whenever driving conditions (speed/load) are such that sufficient high temperatures are generated in the system.



"Active Regeneration" occurs when passive regeneration is not accomplishing sufficient soot removal, thus the filter could become clogged as a result of soot accumulation, so sensors direct the injectors to place additional fuel in the exhaust system, to raise the temperature of the gasses to a degree where the process can proceed. This additional fuel raises the EGT, so that the process can be observed by the driver who is monitoring gauges, and notices a sudden, otherwise-unexplained EGT increase.



Ideally the "Active Regeneration" will be initiated only as actually needed, so that excessive fuel consumption will not result.



It seems that getting all the bugs out of the system is taking a bit of tweaking,... thus the series of TSB's and "flashes".



You might want to search-for and read the thread titled "Understanding regeneration".

 

[Wolfy]

Oh, when will it all end?

I don't like being on the receiving end of the truck engine jokes like the Ford and Chevy guys were for so long.

First I find out that some people have different opinions than I do about the Easter Bunny.



Then religion.



Then sex.



Then politics.



War, too!



And NOW someone doesn't favor my particular breed of truck?



It is almost too much to bear!!



Where is Dr. Kevorkian when you need him?

 

[QWaller]

Didn't say I was losing sleep over it. Just that as I am on my 5th CTD now, I have enjoyed for a long time seeing the Cummins on top of the reliability heap (IMO). Just seems that may be changing. But heaven forbid anyone say anything the least bit negative around here. :-laf

Last seen toasting marshmallows in the wake of an actively regenerating 6. 4 Powerdork

Scrutinizing is a good thing. It makes you pay attention to the details so when something does go wrong, you are armed with some knowledge. As stated above, consider the source when Ford guys talk smack about Cummins.

I'm scrutinizing the heck out of the 6. 7L since I really want one. But, I'm not going to buy one just because. My 04. 5 is working really good and I haven't had any major problems with it at all and I only have 11 payments left on it.

Talked to him on the phone Monday, he approaching 100,000 fast and all is well.

Pathetic story:



Was at a local small town summer "fair", and saw a nice older Ram parked at the curb, with a coveralls-type standing next to it. In a congenial manner, thinking I'd ask how how liked his rig, I asked if "this is your truck?"



In a surprisingly surly voice, he stated loudly and adamantly "Nah! I don't like Dodges!" I knew at once that here was an open-minded man.



Sad to see someone with such a need to establish his truck-religion in that tone to a friendly stranger. ( I mean, how small IS it, for heaven's sake?)



I didn't ask what he DID like. Probably would have been attacked if I didn't seem sufficiently impressed

I'm scrutinizing the heck out of the 6. 7L since I really want one.

I did too. Now that I bought one, I'm still a scrutinator, scrutinologist, scrutinomoner, ... whatever.



Nothing like a $50,000 committment to keep your attention focused.
