    Start to worry if it gets bad enough to run the engine and you have to stall it with the brakes

    1hz? Don't worry about it, just keep oil up to it

    My old 4.2 turbo diesel will smoke like that. I've found different brands of oil give varying degrees of smokiness as the k's get near towards next oil change. I don't like the oil they use at those "oil changers" (Delco??) it was smoking in no time

    The valvoline will be fine seeing as you already have it

    Mobil Delo will give you good protection as well

    It's not drinking 5L of 15w like my 3 yr old Skoda did every two weeks so I think you're fine mate.

    Yeah I think it's the draw sat the rings you're getting under load down hill. Just monitor your oil usage.
    Eh @northdude ! Being a mechanic you'll have a better eye on his.

    You want me to send my boys around @223nut.

    Blue smoke is generally, burning oil, ie worn engine components, turbos seals, rings, valve guides,
    white smoke is either burning coolant or water, or possibility incomplete combustion, ie a rag in the air-intake, no air, raw unburnt fuel.
    Black smoke is over fueling, poor combustion, or starving for air, ie plugged air filter, poor injector or fuel pump, failed turbo.

    This applies for the older, non common rail engines, the new electronic bastards, tend to reduce and delay fuel so even when something is failed, may not show any black smoke.

    Went for a drive this arvo, no smoke once out of low range. Changed oil anyway and been for a 2 hour drive (to get a pie...) no problems. Cheers for the help guys, think it must have sucked a bit of oil somewhere or just working a bit hard in low range engine braking, first time it's done that though.

    It is quite normal when engine braking for long periods.
    Piston rings are forced out against the bore to seal by firing pressure of the power stroke, so no power no rings being forced out against the bore to seal and scrape the bore clean hence when you put some load on the engine you get blue smoke for a breif interval till the oil that has worked its way up past the rings is burnt off.

    ok heres whats going on from what youve said without seeing the vehicle its sucking oil down the inlet valve guides when theres high inlet vacume ie valve guide seals are probably a bit hard but no doubt some expert will have a more scientific idea that they read off the internet or possibly pcv valve but the first thing i said would be it

    Everyone loves that two stroke smell. Turbo in my truck is about poked, oil getting past the seals and blows a bit of blue under boost conditions, must get onto that!

    Edit: probably due to giving it death in the snow, not that I would drive like an idiot eh @223nut.....
