    puff of blue smoke on hard acceleration

    Hi all

    Jaguar 3Ds

    I have noticed in my rearview mirror, puffs of what look like blue smoke from the exhaust, but only on hard acceleration ie when the second turbo cuts in around 2500 rpm its only for a few seconds, and after that if I put my foot down there is no more blue smoke, but after some slow running around town it again will give out a puff of blue smoke, it is not using any oil, I have just done an oil and filters change, and it is still the same, is it possible that the second turbo is passing oil through an oil seal into the air side were it remains until I give it a bit of teddy and the small amount of oil in the air side of the turbo is sent into the engine, I can't think of anything else that could cause this kind of problem, any idea's from members of the forum.

    Thanks John193

    What sort of driving do you normally do and what is your current mileage ? Local driving will build up crud in the EGR which will burn off in the exhaust when you floor it.

    Oops! Being a newbie, I think I may have put this in the wrong section.
    Can a 'Mod' move it please?


    Evening all.
    I'm a newbie and this is my first post, although I have been lurking for sometime. What prompted me to join is this old post.
    Sorry to resurrect this but these are the exact symptoms I am getting at the moment.
    Did you ever get this sorted? If so, what was it?

    Any help/advice would be sooooooo much appreciated.

    I have noticed mine giving a pretty good smoke screen during wet weather when the engine has not yet come up to the right temperature.
    When flooring it, down a motorway ramp for example, it gives ashamingly lot of blue smoke.
    But only at moist conditions close to zero temperatures.
    Dry conditions, no smoke screen.
    ?
    2l diesel.

    I would rather prefer black smoke screen...
    Blue is embarrassing.

    Blue equals burning oil.
    Black equals excess fuelling or possible air starvation, e.g. A blocked or dirty Air Filter.

    Range Rover do a “mod kit” for this issue on the range rover’s with the same 3.0D twin turbo but I can’t find Anywhere on the Net if it fits the Jaguar XF. I’ve been experiencing the same issues now for 15k-20k miles now... same big puff off blue smoke, worst if it’s been idling in traffic. Im adamant it’s the cause! It’s well known on forums and there’s videos on YouTube of LR discos doing the same as my Jaguar XF.

    See copied and pasted below...


    THE 3.0 TDV6 HAS AN ISSUE WITH RETURNING EXCESS OIL FROM THE PRIMARY TURBO CAUSING OIL TO PASS THROUGH THE TURBO HENCE THE IMPRESSION OF A TURBO BURNING OIL AND BLUE SMOKE FROM EXHAUST. USUALLY WORSE AFTER IDLE AND UNDER LOAD FROM STAND STILL.
