Common Rail 5.9 burning oil (I think)

[Jack Jensen]

Going to start this off with some background information so y’all can get an idea of what’s going on.

I have a 2006 2500 4x4 4 door long bed with an auto. It has 245,000 miles. I bought it 13 months ago and have put about 15,00 miles on it. I do oil and fuel filter changes every 4,000 miles and use Napa oil filter and AFE fuel filter. I run it on an economy tune on my edge tuner. I also have a S&B cold air intake. I am 20 years old so yes I do drive like you’d think, but I do not abuse my truck. I pull trailers every now and again. The PO was an old man and I was told the truck had a camper on it most it’s life. But this guy took amazing care of it. This thing is in amazing mechanical condition and has zero issues other then this new oil thing.

I changed my oil a few months ago. And last weekend I checked it for the first time since I did my last oil change which is bad I know, I usually check it often. But I was 7 quarts low. So damn low. I have zero leaks other then a small power steering leak. Engine is clean. Wondering what y’all think is wrong. I work at a truck shop so I know my way around cummins, and engines pretty good. I instantly thought rings are going bad, but wondering if there is other things y’all could give me advice about on this 5.9.

I live in Ellensburg and this winter was very cold. My truck would warm up for 10 minutes every morning. It doesn’t blow any blue smoke. Sometimes on start up when it’s cold it has some white smoke but every diesel I’ve owned has done that. Before now it has never burned oil. I fill her up last weekend with that 7 quarts and I keep checking and it hasn’t changed at all. It also has never shown low oil before now either. Seems like it only did it over this winter.

Just want to confirm.....7 quarts low? The engine required 7 quarts of oil to fill crankcase to the full mark on the dipstick?

I believe that dam_ , is a cuss word

What did the fish say when it swam into a concrete wall?
Dam.

Well, that’s my joke for the day. Couldn’t resist.

Anyway, Jack, when you say it warmed up for 10 minutes, is that from a dead cold start and at normal idle speed?

Are you SURE you put a full 12 quarts in it at your oil change?

Ah yes, I guess it can be. Too many years in the army, I didn't read it as a cuss word.

Not to “high Jack” Jack’s thread, but I agree with you on the profanity mfurrh55. I fought hard here years ago about it. I understand what John’s saying, too. Word’s mean different things to different folks. It’s all about how you were raised and the environment you live and work in. To my mother the word “butt” is a cuss word. They left the church they’d been attending for over 20 years when the new “young” preacher used it from the pulpit a few times in a sermon. Two of the most godly men I ever new, both deacons at our church for almost 50 years and both old time farmers, used the word “ship” except with a “T” the way I say “crap”. And to my wife, if you’re going to say “crap” you might as well say “sh_t”.

Now, back to Jack’s oil thirsty ‘06.
