    Blue smoke, oil & citrus odor

    Ok, I've found how to start a thread! lol
    i had i
    So, my 2015 ECO has125k, km, or 70k, miles. It seemed to run very well when I purchased, only 5000km ago. Knowing I wanted to get rid of the DEF and EGR system, I had it tuned and deleted in Red Deer, Alberta.
    The tuner does alot of eco diesels, and his dyno results are pretty impressive. I think it was 275hp, and 515 ft/lbs.
    Once I installed the flo-pro exhaust kit, I noticed I was blowing blue smoke, and strong odor of burning oil AND unburnt diesel. That strong citrus type odor.
    Strong enough to make it unpleasant to be parked with windows down. In fact BURN your EYES strong...

    When I did the EGR delete, I noted close to 1/8th inch oily, soot build up on the egr tube.
    I now have the truck well dismantled to access the motor, take my time and fix any issues.
    The above symptoms, along with a bit of what I thought was turbo scraping noise led me to think, maybe a bad injector along with worn out turbo.
    Now that I have dismantled to the point of removing the intake for cleaning, removed the injectors, and removed intake and down pipe from the turbo, in preparation of removing the turbo...
    The turbo feels fine, quite good actually.
    I pressured up the injectors to 4500lbs, and held pressure, not a drop leaked from any of them.
    The two problems I thought I had dont seem to exist.
    Im thinking compression test now...

    I'll post some pics of various parts, including intake soot, and would really appreciate some opinions and insight.
    Thanks!!Blue smoke, oil & citrus odor-20190812_205504%5B1%5D.jpgBlue smoke, oil & citrus odor-20190813_131921%5B1%5D.jpgBlue smoke, oil & citrus odor-20190813_150559%5B1%5D.jpgBlue smoke, oil & citrus odor-20190813_144014%5B1%5D.jpgClick image for larger version.

    Maybe the pics can provide some ideas to those of you who know these motors better than I.
    I'm wondering if a catch can could help with the burning oil, as it doesn't appear to be the turbo seals causing the blue smoke and burning oil.

    Are you sure it’s burning oil , by checking dip stick ? If burning oil maybe valve guide seals, does it smoke bad when first started then clean burn ? If smokes oil heavy first start because oil leaks past valve guide seals into the combustion chamber...

    Now here’s the deal make sure your tune isn’t causing your smoke issues, very common with certain tunes. BTW all tuned modern diesels stink and burn your eyes...

    I too have a cummins, 2006, with smarty & 90horse sac style nozzles.
    It burns cleaner by comparison & smell., just for reference.

    However the tune on the ECO has likely increased the fuel fuel pressure, correct?
    The blue smoke seems to last until near running temp, maybe longer...
    Which made me think hot side turbo seal...
    I'm going to pull the turbo anyway, planning to up-size to the 22/60

    How did you determine it was burning oil ? I’m leaning towards your tuning is creating your smoke ...BTW who’s the company that did the tuning?

    Damn that block looks naked!

    I don't think I would have torn that much into it for a little smoke on a tuned truck but your probably more comfortable with the tear down than I would be.

    What got me thinking it was burning oil, is simply that oil burning smell..the one you get from any vehicle burning oil, & making blue smoke..
    I agree the tune could cause blue smoke for sure.
    The company who did the tune is called LightSpeed Innovations, out of Red Deer, Alberta.
    I honestly havent driven it enough miles to determine a volume of oil consumed.
    Pretty much parked after I expected the turbo was toast, which it def isn't.

    The PCV system is suspect aswell, I think...?
    A nozzle from the timing chain straight to the turbo intake..??!
    That's asking for oil burning in my opinion

    If that is the stock setup I don't think it is a culprit of oil consumption. Ive got 72,000 on mine and never added a drop. Several users have many more miles and more towing/harder use and don't have to add either.

    If you have any oil in your intake, intercooler, etc.
    It is from the stock PCV set up...picking up oil at the timing chain, pushed through the turbo, to Intercooler, and then intake...
    If any are oil free I'd be shocked.
    True?
