Soot buildup

[ACF]

I have been hearing some talk of soot build up with the 6. 7's if they are not used to tow or at least run at hwy speeds on a regular basis, is this true for all of the engine's, or just a few? And what is the prognosis/cause and cure? Is this something that I am going to have to live with if and when I get rid of my 05 5. 9 for a new one?



Also I have been doing some reading on Ford's new 6. 7. They claim that by cooling the exhaust gases after they go through the EGR valve that this will not be a problem for them, any info on that? Thanks.

All diesels with EGR will build up soot in places. Cooling the egr does not eliminate soot. The new software the 6. 7 is shipping with now does seem to work pretty good at keeping the system working good. Cleaning the system is a required service at about 67500 mi

Keep in mind there is a lot of misinformation floating around. None of us knew anything about the new engines and their emission control equipment when the trucks first appeared and are only slowly learning a few things.

The first ISB6. 7s experienced sooting problems, few '08s have and perhaps no '09s. Cummins/Dodge engineers have been continually addressing the issues and issuing computer software updates to revise parameters like the regeneration process. The three dealer Cummins techs/TDR members who post here strongly urge owners to have the latest reflashes done.

The Chassis Cab trucks have a little less emission control equipment and have been essentially problem free. My C&C is approaching 60k trouble-free miles and EB whose '07 was used as an oilfield hotshotter truck pulling a heavy trailer daily has over 200k trouble free miles.

I would buy a a new '09 or '10 Ram w/ISB6. 7 with confidence that it would be trouble free.

The Cummins ISB6. 7 is based on the proven ISB5. 9 so the long block is bullet proof. The soot issue caused by the 2010 federal emissions laws are solely responsible for the minor but annoying problems experienced by early 6. 7 engine owners.

The anticipated new Ferd engine is all new, unknown, and unproven based on nothing Ferd has in their inventory and based on no in-house experience with diesel engines. If you are concerned about the few new Cummins engines that have reportedly had smog problems stop and consider the problems new Ferd engines are likely to experience.

Ferd claimed that the all new Navistar 6. 0 engine was a great new engine also!!! After the 6. 0 cost Ferd and Navistar hundeds of millions of dollars in warranty claims, truck buybacks, lawsuits, and lost sales they claimed the 6. 4 was a great engine. It has not been as bad as the 6. 0 but Ferd has ended their long running contract with Navistar and designed their own V8 diesel engine.

I wish Ferd no bad luck but will be sitting on the sidelines watching and waiting for the review and results. NO FERD in my FUTURE . . . . and certainly no Nobama Motors Isuzu in my future.

You can run it until the DPF finally plugs solid and the engine quits running. If the EGR is stuck open it is loading the system with soot. Your doing more harm by continuing to drive it. Get it in, get the EGR repaired and the latest flash.

 

[Boatwheels]

thanks for the info I am a 1000 miles from home I have had the truck to dodge 5 times the egr was replaced the egr sensor the tube was sooted up and cleaned the light would come on after a hour of running now the first time I got a catalyst full. I have a 5 year 100,000 warranty on the emmissions system and dodge says I am responsible If the particle collector needs to be replaced. thanks. . steve boatwheels

 

[sag2]

Something does not sound right. Do you have any more detail from the repairs? What did they write up as the fault(s) they found? What specific codes if any? Why would they say the DPF was on you? There must be more to the story.

 

[HBarlow]

Boatwheels,

Are you the original buyer? Has the truck had any modifications such as magic boxes or emissions equipment unplugged or removed? Has the truck had regular service with approved oil and filters?

Like sag2 above I'm wondering what the rest of the story is.

 

[Boatwheels]

thanks again, Yes I am the original owner. no there have been no modifcations. all was well up to 72000 miles the engine light came on. took the truck to the dealer and they said the light was the egr. it was back ordered for a few weeks. took the truck back they changed the egr the light can on in hour or so. 3 more trips to the dealer with the light on and they changed the egr sensor cleaned the tube the light still comes on. the last time i left it there, they said they called the star program checked for exhaust leaks . all said and done they charged me 410 dollars to tell me all the things it wasn't. they wanted me to approve them to take the turbo off at a cost to me of $400. there is a whistle that comes out of the turbo when the truck went into regeneration. I change my oil the first of the month. use mopar filters the oil I use mobil delvac or castrol rotella. I use the truck in alot of local traffic. I pull boats around long Island for a living I am now in florida with just the truck, no trailer and concerned about driving back. the local dealer here said they would look at it at my cost and There words ( it would be a long process. ) they stock no parts and would be calling dodge on how to fix it. steve boatwheels thanks for the support

Are there any other dealers around the area you could try?? Charging you for warranty work sounds wrong. I find lots of variation in service departments and abilities or willingness of techs to work out a problem.

 

[HBarlow]

Check engine lights and trouble codes are indications of engine problems which are covered under warranty for the five year 100,000 mile warranty period. You are not required to pay for diagnosis or repair.

Either there are details missing from this story or you have stumbled into a dishonest dealership which is deliberately trying to cheat you.

If you have not done anything to neglect or modify the truck or failed to perform proper maintenance with approved parts you are entitled to better service under your warranty contract. I would recommend taking it to another dealer. Look in local phone books for Five Star rated Dodge dealers that will help you.

ACF, we have an early 08 5500 C&C... we drive it like we stole it... and its running always at 65%-75% GVW...

We had some issues when the truck was under 20K miles... now we just drive it... We've not had any issues and frankly if Sag2 was in our town I'd take it in for service, but the local guys really bother me... . so until we get a code we're just driving it...

Sag2, at the 67500 mi service, whats done??

" Drive It Like You Stole It!! "



That is a interesting subject.....



More to come.

Off the top of my head Replace the ccv filter and egr cleaning.

 

[Boatwheels]

steve boatwheels again, thanks, and the dealership in west islip long island said that if I can't prove that I used there oil the cost was on me and the removal of the turbo was my cost. I hope in a day or two I can say I made it back, and I will take your advice and see what other dealers could help solve this problem. I'm not one to chat online but I thank you for your help... steve... boatwheels

 

[HBarlow]

Boatwheels,

You mentioned the brand but didn't say you have been using the specified and critical CJ diesel engine oil. Have you been using CI oil or some unapproved type of engine oil?

If your dealer tells you it is your responsibility to prove you are using the correct motor oil they must have some reason to suspect you are not or have not been following the recommended change interval.

I hate to be skeptical here but there must be more to this story.

 

[Boatwheels]

my question is does the tsb# 18--35-08 apply to my 3500 cab and chassis 6. 7 07 truck? does the g30 recall ? or the new oxygen sensors with the wrap that I read in issue 63 that the dealer is required to install? engine light on and the cat full service required message steve. . boatwheels

I used mainly shell rotella T 15/40 mobil delvac a few times I didn't buy my truck at the dealer that is trying to fix it' don't know them this is the first time to a dealer since new. change my oil the first of the month when I work with it milage per month about 4000 to 5000 my 3rd dodge since 1991 a 91, 98 ,12valve and this one all rotella T oil. I don't have anymore never modified any of the trucks, just blew trannys and rears steve. . boatwheels

 

[HBarlow]

You didn't answer my question of post #16. Are you deliberately evading that question?

Is the Shell Rotella oil you are using rated "CJ?"

The ISB6. 7 engine cannot use the CI oil that many of us used in previous B5. 9s. Use of CI oil will plug the dpf.
