Cummins 2004.5 EGR Durability

[mtncharlie]

Hi,



I know this engine hasn't really come out yet, but how does EGR affect long term durability on the new Cummins engine or the unfortunate 12 valves in California? I really wish they would have found another solution like CAT claims to have done. The EGR and the small engine compartment are really the only things about the new truck I don't like.



I used to live in California and before buying my last Cummins I waited for the 99 24-vavle ISB to come out since even in California they did not have EGR. That was a great truck but I sold it when I went back to school, in hindsight I should have just kept it stored somewhere.



I know on the 12 valves the EGR really did a number on the oil and sooted things up pretty fast.



At least we have the option of getting them up to 2004. 5 without EGR.

I know its not a fair engine comparison, but I have talked to several people with the VW TDI engines and the EGR soots and plugs up some things. Maybe you can find out more on the TDI site.

The ISBe has been out a few years in europe already. The only thing about the EGR that would concern me is the USA's CRAPPY DIESEL FUEL. We need to raise our mandatory minimum requirements to 45 cetane badly!!

What, and make it cost MORE? In salt lake it makes gas look cheap, and it went up in price by 15 cents last week. :{

The VW TDI's with EGR will tend to "silt up" the intake manifold with gunk, to the point of significant power loss. Lousy fuel accelerates the process. Additives, higher cetane fuel, and biodiesel all seem to minimize the problem. On the little TDI you can also pull the manifold, clean it out and reinstall in a couple of hours.

I "seen the 6. 2's come in and wonder how they ran at all. The intakes are sometimes sooted just about full before some people bring them in.

As far as the 6. 5 turbos's the dropped the EGR in after the turbo on the +air pres side of things. Never did fiqure out the logic in that other than not sending all that junk through the turbo.

If the truck has an after market intercooler it will slowly plug it and dripp oil if clamps are a little loose.

The one we run here is highly modified and has a drop tube like the cummins so we can oil up the parking lots not the intercooler.

Lets hope cummins doesn't put that junk through our intercoolers with all the blow-by thse engines have.

I can see it now an IAT sensor every 2'nd oil change.

Wonder if a spent . 22 shell could get stuck in the vacuum line? A shell has been stuck in the EGR line in my Dakota since 30k, it now has 175k and runs like new. The fuel injectors stay much cleaner too.
