    So. After a long chat with RM Turbo's, he doesn't think there's anything wrong with the turbo. With the play in the shaft, he said thats normal, its supposed to, he called the bearing a name to which it draws oil through it for lubrication, which in lamens terms, takes up the bearing free play. Hence why the I can hear the turbo spin down for 30 seconds after I turn the motor off.
    Also mentioned, the amount of oil I used, the turbo wouldn't go through that much, He said I would really know if it was, there be oil everywhere.

    So. Not sure what to do here. Leave it and just drive it or look into it further.

    Atleast I don't need to remove the turbo now. Which is one good thing. Good time to fix the little exhaust leak coming from the dump pipe now its off...

    Yeah not too surprised really I wouldn't worry about a little bit of play. My motor is similar uses a little bit of oil, remember the engine builder asking if I was too worried about blow by as is better to have ring gap on the larger end of the scale as opposeded to tighter as this can result in fubar engine so this may be the case with either either or both? I know it's not ideal but as long as it's not using crazy amount, blowing smoke or leaking just drive it I reckon. Could ask JPC, is funny that it hasn't done it from new but . .?

    Yeah doesn't blow any smoke apart from the black stuff. I could have done it from new Rossco, but I've only noticed it in the last three or so years. My old place, from about three years ago, there was no where level to check the oil, even the garage floor was on a slope. So fluid measuring was pretty much a guesstimate.
    I'll speak with JPC when they re open and get him to go over the engine again. Thanks.

    Mark maybe of interest (worn or crack valve seals):

    Oil Consumption
    Bad valve seals will cause excessive oil consumption. In an otherwise normal engine with good compression, rings and valve guides, bad seals will cause a loss of oil that can be detected on the oil dipstick. By keeping an accurate record of oil level on the dipstick, a noticeable oil reduction due to the oil being burned along with the fuel will be discovered. Bad seals will be confirmed if no oil leaks can be found on the engine to account for the loss.

    Excessive Smoke
    If the valve seals have deteriorated enough, the blue-white exhaust smoke will last longer after start-up and acceleration. Yet the smoke will eventually disappear after long engine operation or during periods of hot weather. Bad valve seals nearly always show an intermittent problem of oil burning, whereas worn piston rings and valve guides will smoke during all times of engine operation and never disappear.
    Yes turbo shaft can have a lot of sideway play and does centralise when she spins up.

    Mark.
    From distant memory , your rear windows are shaded up. You can't see smoke behind you!
    Problem solved.

    From my limited knowledge, if it were valve stem seals, there would be white smoke on startup due to oil leaking down into the cylinders when the engine is not running. I get nothing.

    The inter cooler always has a fairly consistent oily film in it. But the intake side of the turbo is bone dry.
    My original thoughts was the motor, but after seeing the intake dry the turbo must be shot in some way.
    So I removed the intake pipe and had a feel of the impeller.
    Assuming there is supposed to be no play in it. Mine has. Feck!

    So.
    Any tips on removing a Garret low mount Turbo? Never done this before. Just start pulling bits off I suppose....

    Mate that is a REALLY nice patrol .You dumped 8 litres, whats the capacity? Somewhere around 9 to 10? How many ks since you last changed it?
    If I had no nasty shyt coming out of the exhaust and was losing a litre or 2 between oil changes at 7 to 10 ks i would not stress too much?

    What grade and type of oil do you run? Did JPC add extra clearence?

    My TD used to use 2-3L per 5000km when it had penrite oil.
    It used 0L per 5000km for the next 6 years using anything but penrite oil.

    Hi Ben, I was hoping you’d pop your head in. I trust things are well up your way in the land of freedom?
    As for the oil. I’ve run various brands, valvoline mainly. Have switched to Castrol Rx Super as of late . All oils were CI-4 or better and 15w40.
    I’m not sure on the clearance side of things though mate. As Rossco mentioned it could be the ring clearance set when the engine was built??? That stuff is beyond me sorry. I will have a chat with JPC when he reopens about this.
