    yung sedona ko over 1 year old pa lang, mga 13K ang mileage. It passed the smoke emission test 4 months ago, but I noticed even at idling, mas may usok lumalabas compared sa isuzu rides ko. Also, when you step on the gas, may maitim na usok na lumalabas. Even if people say this is normal in a diesel, I don't notice that same black smoke in other diesels. Yung isang sedona ng classmate ng anak ko, they got theirs a few months ahead of me. Mausok din, especially when I was following that unit at the school parking lot, so mabagal ang takbo niya.
    I follow the required 5K change oil maintenance, even had the gunk at the manifold removed at around 11K mileage. Yung cousin ko who got a carnival commented that this engine daw mausok. Is there anything we can do? Or should I stop looking at the rear view mirror kapag humataw ako?

    na solve usok when i had the turbo system cleaned + injection pump re-calibrated.

    Tet,

    The gunk in the manifold is formed when the egr and the vaporized oil mix. It is the black sticky substance that will eventually clog your system.

    I am interested in the turbo system cleaning you mentioned. What did they cleaned in your turbo. I suspect the oil seal in my turbo is leaking into the intercooler. Please elaborate more on the turbo cleaning.
