Dodge 3500 diesel troubles

[cstone]

Reading this thread reminded me of this article:

Less of one emission creates more of another emission and all of it makes the engine more inefficient which causes more fuel to be used which is exactly what the environmentalists say they don't want.

I'm still trying to figure out the whole "piss makes a diesel engine cleaner" thing.

Depending where your vehicle is registered and if you have to do emissions, seriously look at the EGR delete kit. They used to be cheap but not sure what they cost now. The install was fairly easy when I did it back in 2011 on a 2007 6.7 Cummins. I'd recommend taking the time to clean the turbo. Also, make sure you are turning on the engine break every time you drive the truck. It greatly helps to reduce the carbon build up that is famous on this engine.

I don't know what the actual code was. I'm just going by the what the dealer said. I was told by them and have read further that cleaning isnt a sure fix and even if it does work it won't last and I'll end up needing a new turbo anyways. I was quoted 5k for turbo replacement and there's no way that's happening so now I have new lawn ornament.

what the def does is reduce the nox emissions in the exhaust pipe instead of in the engine
to reduce nox you need to have cooler cylinder temps which is done by recirculating some exhaust back into the intake.
now with a system to clean up the nox on the back end higher cylinder temps means higher efficiency and much less egr recirc.

On the 15 liter Cummins 2008-2010 engines recirced up to 25% now with def that number is in the low teens

The early 6.7's will need the turbo cleaned every once in a while unless you delete them. Don't ask in the forum how to delete, some of the mods get a little pissy when that gets discussed vs other "illegal" things that are discussed frequently.

The VGT turbo's get gummy unless you are working the truck most of the time. When I was pulling trailers all the time, mine never had an issue. Started using it as a grocery getter, and it got clogged up and needed cleaned several times (thankfully under warranty).

Since the emissions stuff rusted off, I haven't had a problem, get 22-26MPG (sometimes 18, if I decide to use all the extra ponies all the time), oil stays cleaner longer, etc...

EGR delete's are easy on the early 6.7's. I just made my own plates and bolted them on. I also have an aftermarket intake horn, so that side went away anyway, but an EGR delete could be $10 in steel and an hour or two of effort.

Does that make the engine more efficient? More MPG or more HP per gallon of fuel burned?

It seems that the more NOX reduction the more CO2 produced and vice versa. Pick your poison but I would think that burning less fuel is the best route.

No, it doesn't make them more efficient. Sort of apples to oranges, but my Dodge had the DPF/EGR only system, and our Chevy work trucks have the DPF/EGR/DEF system that all new diesels have. The new systems get worse mileage than my Dodge, in factory condition.

The EPA doesn't care about efficiency. They care about exercising their might within their fiefdom.

I would suggest contacting CDC (Colorado Diesel Crew) on Facebook...

They can likely suggest a Diesel mechanic that can give you better options than the dealers can/will.

I can recommend BH Diesel in Colorado Springs, but don't know in Trinidad

I think that was the point in the FEE article. Most of the diesel emissions garbage is the EPA enforcing more California nonsense for the purposes of destroying or controlling the diesel industry. All costs in commercial diesel use is passed on to the consumer. Why would the government care about soaking us for money that most of us don't even think about as another hidden tax?

looked like $880 plus $400 core deposit for the turbo on rockauto.com...surely you can find a shop to R&R the turbo for a reasonable price

I found this, some guys claiming unplugging the VGT temporarily got them through until they could afford a permanent fix...
