Does anyone know Chrysler maintenance codes?

My CRD just went over 36,000 miles, and I am unsure if the fuel filter has ever been changed. I have a printout from the dealer where I bought it of all service records, but since they are in code, I am not sure whether or not one of them is a code meaning "Fuel Filter/ Water Seperator Change". Can anyone help?

Also, went under it today to change the oil - my first time to change oil on a diesel, ever. I was amazed at how black, nasty, and smelly it was. Is this normal? Kudos to the dealer for changing out the Allen bolt drain plug with a hex bolt. 22 mm or 7/8 SAE, but the 22mm is a tighter fit.

can't help you on the filter issue, but I can on the oil. To answer your question, yes. Diesel oil is nasty, some are smelly, and it stains every thing.

no idea on the filter code - however the oil

"black, nasty, and smelly" - is the result of the EGR -
dumping carbon into the intake manifold

and clean oil will look like that in about 10 minutes

Actually, the black nasty is soot, the main byproduct when Diesel fuel is combusted - gets into sump oil via blowby - earlier Cummins 5.9L turboDiesel medium-duty engines quickly blacken fresh oil, and they do not use EGR, instead preferring the elephant hose concept of blowby relief - EGR is why yer intake manifold looks like a coal mine.................

OK, so I'm going to ask a question here: - please don't jump me to bad, I am a n00b -

How do you get that to stop? Is it possible to stop the EGR from dumping soot into the intake? (I think that's what the SEGR is, but I have never found a complete explanation anywhere, so I'm throwing it out there. . . )

SEGR is a module, inserted into the wiring harness, that disconnects the EGR solenoid, and tricks ECM into thinking EGR is functional when it is not

Every diesel engine ever made turns the oil black within the first five minutes of operation...Regardless of whether or not it has an EGR.

Or less. Some of the engines at work are black as soon as the oil hits the pan

We have a 60 series Detroit diesel at work with 15 000 hrs and oil still looks brand new when doing oil changes after 200 hours. No EGR, crank case vents to atmosphere.

Doesn't the 60 have an oil centrifuge? Why are you changing the oil if it is still in good shape?

Thanks for the reply. I am Not sure, but I can check. I know they have 3 large oil filters: 2 full flow, and 1 by pass filter. What would the centrifuge look like and how does it work.

We do the scheduled oil changes every 200 hours because too much relies on these engines to have any break downs. This interval seems to keep our oil samples coming back okay and I think it is a fairly standard interval in industry. I have always wondered why these engines keeps such clean looking oil so I will be interested to see if it does have something like that.

I finally found the engine manual and the series 60 does not have a centrifuge from the factory but it does have a LOT of filtration. If your units have bypass filters they do basically the same thing as a centrifuge.

The industry standard for all CAT equipment is 250 hours, with some of the newer ACERT engines moving to a 500 hour Interval

Thanks for the effort. So you think the large amount of filtration is what is keeping the oil so clean? I am going to look into oil centrifuges and see if we have any on our other engines. You've also got me interested in learning how the by pass filters differ from the full flow since they look so similar. Thanks again, this is great learning for me.
