You were right on about most of your post, until this. This is the doing of the Sierra Club, the EPA, and those powers that be that think any-type of pollutant should be immedialty banned from the planet. Sorry to say so, but Cummins did the best they could with the time, money, and talent avalible, however the next step in '10 and the Tier IV emisisons are proving out to be much more challenging.

And NO, a dealer isn't going to document removing DPF's, and neither shoud one of us. It's why I still drive a 12-valve, to be honest.

 

A dealer recommending that?
Sounds like they are slapping band-aids on a problem that has a much deeper problem, just trying to get angry customer's out of their face.
I'm all for chopping stuff off my own junk, but if a brand new truck that I just paid x amount of dollars for was screwing up still under warranty, and a dealer suggested that, I would be PO'ed for sure.

 

It isn't a band-aid though.. Dodge installed a system that pretty much causes reliability problems because they HAD TO to be compliant with the EPA BS. By removing those devices, it fixes the problem.
Not a band-aid fix at all, the DPF & EGR ARE the problem.

 

The PCV should be included on this issue. Its gone on my truck after seeing oil heading back into the turbo. Since the surgery on all of this my truck uses less fuel then my 5.9 07 3500 4x4 and prior to the surgery, it used almost double!

I understand that they are the problem.

But they should be coming up with better answers to these problems as so called professionals then just cutting off these parts, and then failing emmisions if your locale has/will have/them.

Read the whole reply please.

 

Well, heres something of interest to those concerned with emissions.
When I did the DPF surgery I had also increased the black smoke out the tail pipe. I was not wanting this. However, when I did the EGR and PCV surgery, I can only get a very slight haze on heavy throttle that can only be seen at night when headlights from the vehicle following shows it. The same or similar as when all the emissions stuff was intact. Since there is no emissions regulations and/or testing UP HERE, I might find a place in my travels to see if it passes or not. I have a feeling it will be very close. After learning as much as I have with talking to Environment Canada, I would not be surprised if the truck passes. If I can save non-renewable resources and not blow black smoke, I think that has some value for more then just me saving $ on the fuel costs. Afterall, how does all this emissions stuff have a greater value if we are using nearly double the fuel to comply? I still cannot get my head wrapped around the need to go drive the truck and burn more fuel at my expense to comply with the requirements of this new emissions stuff. Makes no sense to me that we should burn up more fossil fuels to do this.

On Edit:
What comes out the tail pipe of a truck with all the emissions components intact while the DPF Regeneration process is active? When you burn something, a chemical change occurs...what is it during this process and where does it go when the DPF is cleared? I recall that some emissions that are invisible are often more harmful to the environment then those we can see. Does anyone know?

 

So did you do just the PCV or did you do everything at once?

The PCV you speak of is the one sticking into the inlet to the turbo, correct? What did you do, just put a hose on it and stick it beside the block like the 5.9's originally did?

 

Thats the one.
I did the DPF first and then about a week later I plugged the inlet on the 90* on the turbo and the crankcase now vents to the atmosphere.
Then after about 3 months and too much smoke I did the EGR. I noticed if I did some city driving and then got on the throttle, the truck would dump lots of smoke. Not anymore. A different air intake can help too since the factory filter is like a large brick in there.
Hopefully I did all this soon enough as to not experience any of the long term ill effects of all that stuff being pushed back through the engine. Its a nasty sight inside that intake when you do the EGR!

 

Come on now!! Where is are intake at!!!

After my pipe delete this truck smoked like my bros. 12 valve, after doing the egr delete no smoke no matter what!! Edge all the way up and no black plume! The EGR is what is killing these trucks!!

Guess I'll be needing to do the PCV mod on my Dad's truck!

the h&s kit for my cab/chassis i have doesnt have the bungs welded on for the back pressure lines. they say to unplug the lines off the sensor on the trans, but i see badp has a code free kit and it has the bungs welded on to keep the lines. why the difference? it seems to me it would be better to keep the back pressure sensors in place?
