If I recall correctly..... @Cummins12V98 had to replace a lower charge air cooler hose due to perhaps the clock position of a spring clamp rubbing a slight hole in it.....but I’m not sure if that would have had anything to do with his OA or not.

^^ Interesting that the clamp position could cause a pinch point / hole. All good reasons for me to use the provided spot in the side of the fender liner to continue to change the filter... Sorry Ron I couldn't resist..

I understand and I appreciate the ribbing!

I have mentioned it before If I had not removed the intake for oil changes I would have never seen this and I would have possibly had a real issue along the Interstate.

GS, good memory! This was replaced 11/2018 and oil was changed 10/18 my first bad silicon was 10/29.

Makes you go HMMMMMMM Thoughts???

Iron alone could be camshaft, rockers, bent pushrod rubbing.

I would look at the turbo compressor nut and see if it's packed with dust. Cummins did that here, checking for an intake leak, when we were looking for the damned knock on my 2003.

Even with after asking RAM you can continue to do UOA and decide on if it's getting worse: trade the problem. Staying the same you can ride the vehicle shortage out till things get back to reasonable. I would still smoke test the intake, charge air cooler, etc.

Your Iron numbers look like my 2003 5.9 with the wick turned up. My 2018 Iron was 70 break in oil and is 13 now.

"I don't do UOA."

Your truck your money. You loose a head gasket or get a fuel leak: you dump the warning with the oil change. IF it's slow enough to catch before it completely ruins the engine. Warranty is nice, but, IMO a easier fix is catching and correcting it before you have to wait for them to yank the engine and find/ship another one. I pay $30 a year for two samples with postage. I found out via UOA that my selling dealer used the wrong grade of oil or they used poor quality oil that sheered down to 30 weight for two oil changes.

"RAM won't do nothin..."

It's for sure "No." unless you ask. One would have a better NQA case if they do the required 6 month oil changes. Yes IMO it's wasteful, but, not even a ROUNDING ERROR vs. cost of the truck new. 7 years of additional oil changes vs. 1 a year is like $700.

We have had other OEM's DO SOMETHING as mentioned over UOA and maybe this is why Dodge is known as "Tinplate" to old retired fleet managers. Of course with a fleet of 600 and dealing with the #1 Chevy dealer by sales volume in California ... the company got a reduced price on a order of new pickups over "early front end trouble" some in the current fleet had. Transmission failure in fleet manager pickup just over X miles of warranty "Courtesy" covered. POS R4 compressor sold as a part for his private Yukon = SOL.

That said IMO RAM is making an effort to improve given the CP4 "We agree it's a problem and will replace 100% of them." and finally movement on the V06 recall, sadly, only if you take action.

Do you record the idle hours and drive hours every oil change as well? If so....it’d be interesting to see the total hours for that interval.View attachment 132775View attachment 132776

Great recommendation!

So back in the day 20-25 years ago when I first joined TDR and bought my 1999 new. Oil sampling was all the rage . I don’t know why but it was important to some. Oil brand debates abound as they do today. And what brand oil filters etc etc . I have a Cummins dealer in town so I went with Fleetguard oil and fuel filter. K N air filter where the rage so that went in the air box. I cleaned it with simple green and let it dry and recoiled. I had two of them so one was always ready to go. We have volcanos here so we could get the dust. Changed oil every 10 k miles and at 5 k pulled the oil filter and added make up oil. I never was trying to push the limits of my oil and filters being a low mileage driverMobile 5/40 Delvac synthetic .Oil was was always black from soot but appeared good. So 34 times my hose came off 34 oil filters Two clamps not hard. Never were loose turbo normal little bit of dirty grease etc 170 k miles. I never did oil testing never really even considered it. Why would I I always wondered why folks were doing it . What if it came back bad what would I do ? My warranty was gone soon after I bought truck Bombed

I did the same with my 98 12V. Test said I could go longer but stayed at 10k n filter at 5. The oil was dark but not black. Mostly freeway miles.
