Soot buildup

" Drive It Like You Stole It!! "

That is a interesting subject.....

More to come.

I've noticed when pulling a hill that my EGR is at 94. 9%, which is the max I have ever seen. Good or bad? Part of your new topic?

Boatwheels, delete your emissions crap if you're safe from EPA. Sounds like you have the perfect truck to get rid of that junk.

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.

I read this post previously but the meaning of your comment about a stuck open EGR loading the system with soot didn't register at the time.

Rereading the prior posts to refresh my memory of this thread just now I read your post again and now am curious what happens when the EGR is removed or disabled.

Does your post mean that when someone removes the EGR valve, unplugs the EGR wiring harness, or uses an aftermarket delete device soot is being continuously recycled from exhaust to intake?

Harvey Barlow Im sorry I'm not being clear. I used rotella 15/40 always. In the first months I never looked at the container. Do you know when the rating cj started with the shell rotella? the truck shop said it was the anti-soot and it was the right oil. now I bought the delo heavy duty 15/40 cj low emissions. thanks for the help I will try to be more clear. steve... boatwheels

If you're hauling commercialy and get DOT inspected every so often and if NY has emissions testing, I don't think there is a safe way to do it.

I stay mostly in state and MN doesn't have emissions testing anymore. I worry about it, but not enough to stop me.

I do alot of boat hauling in new york. the truck is registered in flagler county florida that has no emissions. dot here checks ,but mainly tires brakes safety equipment. I keep my stuff in good shape and fairly new. ran into a car hauler and he is ready for his third dpf filter and has lights always on. the light on now in his truck is for rail pressure. is there a way to know if the egr is open or closed. the truck has the catayst full on the display. steve. . boatwheels

I'm still here, some of the EGR stuff will be in my next post. There is a lot of stuff that will be in it...



Be back soon

Boatwheels,

The new CJ oils were introduced about the same time the new ULSD fuels and the Cummins ISB6. 7 engines were introduced in the '07. 5 trucks in late '07. I don't remember exactly what month, maybe someone else knows.

ULSD fuel and CJ oil are apparently crucial to the DPF. Regular use of LSD diesel fuel and/or CI motor oil will contaminate and plug the DPF much sooner than its designed service life from everything I've read.

thank you for the answer. the oil I used was correct ,all the fuel I used was correct and the dealer has no grounds to not cover this problem I am having. I went to another dealer and they said they can't touch my truck because another dealer worked on this problem and they wouldn't get paid from dodge. they said to call dodge and get a case number and go from there. If dodge approves another dealer to work on my truck, I can switch dealers. steve. . boatwheels

They also are blowing smoke up your ... They can work on your truck with out worries of not getting paid. The corporation does not refuse payment on a second dealer doing the job over. They just do not want to take on a problem

The reason for the use of CI API formulated motor oil is because of it's low ash and low sulfur content. High ash content motor oil adds to the content of the particulates that can be trapped in the DPF filter. Sulfur in in the fuel and in the motor oil contaminates the NAC which in turn reduces it ability to absorb NOx (simplified Explanation). If you were to use CJ API formulated motor oil it would cause no more soot than a CI API formulated motor oil. Also if you used a LSD (low sulfur diesel) fuel as opposed to a USLD (ultra low sulfur diesel) fuel, The soot output would be no more than normal. We have seen EGR valves sticking and causing a excessive amount of soot which inturn causes a lot of problems. If you have had multiple EGR repairs done on your truck and still ending up with soot loading issues then it would seem to me that the Dealer is just fixing the results of the problem and not fixing the problem itself.



If the Dealer feels that you were using the wrong motor oil, then it is there job to prove it. If there thought is that the motor oil is causing all your excessive soot problems, Then they are Highly misinformed.



Find another Dealer.

This Emissions systems on the 6. 7L are half baked ideas meant to meet the CARB/EPA requriements. This is a relatively new technology that, IMHO, cost the owner excessively in reduced performance, increased fuel consumption, unnecessary repairs and an unreliable vehicle. I'd like to see what the impact of the additional fuel consumption is, in terms of additional environmental impact, vs running your engine well tuned and omptimizing your fuel consumption...

Another case of knee jerk reactions that are not well thought out nor executed. Add in the dealership BS and you gotta give your head a shake!

 

[MullenaxM]

Your only half right, This is not a new technology, NOx absorbers have been around since the late 70's. DPF's since the mid 90's, EGR valves are late 60's technology. VGT's are new. Computers have been around since the late 40's.



But you are right, If the government did not mandate that we have cleaner air, You can be sure that we wouldn't.



Mike

 

[hwebster]

I stand corrected, possibly the current configuration/implementation is arguably new... The cost v benefits do not add up to my poor little puddle of gray matter... Are we getting cleaner air? I've pulled my DPF and I don't blow smoke, in fact I would have to work at it to get any significant smoke from my unit.

The number and frequency of mechanical/computer related failures coupled with the loss of efficiency, economy and power just don't add up...

Time to let some innovation take place... There has to be a better way!

 

[Bob4x4]

It is crazy that they mandated diesels to be cleaner than gassers,but trust me your truck puts out a lot less pollutants with the aftertreatment in place rather than sitting in the corner.

I agree! Smoke is just the visible part of the polutants. Only the smallest parts of the smoke are the dangerous parts.

thanks mike,

There is another dealer in riverhead new york that they say does some work on diesels. steve boatwheels
