    Blow by is created by combustion gases passing thru the piston rings/valve guides into the crankcase, if it's excessive it's time for a rebuild!

    My truck has blow by, but does not use any oil, having blow by, doesn't necessarily mean it's time for an overhaul

    The question is how much and how often are you adding oil?

    If your truck has the Acert engine which I am assuming it does, it will have blowby. It is caused by oil mist from the vva's. Mine smokes like a freight train while it is at a idle. I maybe burn a gallon of oil between oil changes.
