EGR (oil dirty fast)

[MartinBlair]

My 04 in California has EGR. . My oil gets dirty, (very dark) after 1000 miles. . Some have said you lose performance, (because egr has no oxygen) and causes sooting of the oil, thus causing dirty oil quickly. I'm also told that EGR was done in 1st half calif 2004's to rid of a tiny bit of NOX that they needed to pass new 04 EPA reg's. . Does anyone know what percent of total air intake is oxygen robbed EGR air??? The truck seems to run awsome with the EZ edge. . Can anyone help me with the EGR questions and may give some advice on disarming this thing. (only temporary of course. Just off road use while disarmed. . ) Thanks, Marty

I thought the EGR was totally ditched and never happened

Only a very small percentage of total air flow will be EGR. Nevertheless, if your truck does have it the oil will blacken rapidly. But EGR was a major driver in the development of CI-4 engine oil... it's meant to trap a lot more soot, so you shouldn't have anything to worry about. Just keep up on regular maintenance... change oil every 3000 if I were you.

There is NO EGR on your 04 engine.

the 04 had egr until 01/04 when the 600 went into production . Egr is not on the 04. 5 600 turbo

 

[lmills]

if 04's have egr, it wasn't all of them. It has to be CA models

What the heck are y'all talking about???? I've never heard of Dodge using a Cummins with ERG in the 3G trucks. From what I've heard until the Cummins 600 (No EGR) came out, CA only had the option for a SO Cummins (No ERG) to meet emissions.

I guess everyone is not clear on the EGR thing and Dodge Cummins engines.



For the record:

There has never been a Dodge/Cummins EGR common rail engine produced for consumption, sale or public use in any state.



The only B-series Cummins engines with Delayed Exhaust Gas Recirculation are made for commercial and recreational vehicle use.

These industrial engines referred to as ECHO's.

They have a rear gear train, typically an air compressor, and a VGT turbo.

The ECHO engine with EGR is a different animal than what is produced for Dodge Ram.

So then... uh... Why is Marty's oil getting dirty so fast?

Marty,

I would check the air filter.

Also, I ensure that all hoses and clamps have been installed properly and not letting unfiltered air into the engine.



The Edge box and its fueling will add to the soot content in your oil.

Diesel oil contains soot control additives.

Dirty oil can be an indication that you are sticking your foot in the peddle alot, and that your engine is overfueling (edge box).



When I first purchased my 99 the oil would stay clean for 3k miles.

After I started to modify it, it wasnt 1000 miles before the oil changed to complete black or a real dark brown.

Justin, I just left the dealership and had a lond dicussion about the EGR that is on my early half 2004 CTD. . (California only) What basis are you using to saying it does not have one??? Thanks, Marty

Ummm... . Martin, did you happen to notice where Justin is from? Who do you think his employer might be?

Dude maybe they sold you a duramax.

Martin,

I am employed by Cummins. I work at the plant which manufactures all the Dodge Ram B series engines.



I observe, work, test, and assemble as well as repair these engines as part of my job.



Your dealer, as well as yourself have been misinformed.

I would ask your dealer to show you the EGR system on your truck.

Do not mistake the EGR system for the turbo charged air system which is supplied with your engine.

That would include intercooler, and all plumbing associated with that.



No California Dodge Ram Cummins engines left the plant with an EGR system.

I always heard, sort of a rumor, that diesel oil always turns black quickly because of soot like what gets on the body if the exhaust tip is not long enough.

That would be fun to watch ... I'll bet the dealer and/or salesperson will have a hard time just getting the hood up!



Be a good test for the "service techs" too!

Justin,



If my early 2004 does not have EGR I appolagize. I guess I would ask the folks out there if pressure boxes cause more sooting thus causing oil to get dirty sooner? My truck only has 6000 miles on it and I have changed the oil 3 times. I am however glad to know that my truck has no EGR, but I can't understand why the oil continues to dirty so quick. Thanks for your input. Marty

Ron Flourance,

Your post also said that Cummins LO CARB models for Calif built in late 2003 and sold as early half 2004 in calif were equipped with EGR. . Would you please share where you got this info or how you know this?? Thanks, Marty

Martin,

Does your truck smoke?
