After doing my homework I think it may be possible that I'm looking at more than one issue here is it possible that the smoke could be a bad turbo seal and that the gray smoke is oil burning and dose over fueling give a black smoke?

HI thanks for the response

Sorry I should of been more specific the smoke is blue gray

the smoke is constantly coming out and increases with acceleration I'm also losing oil with no sign of leaking (I have done maybe 500 mile since last oil change) And lost half oil

I have checked turbo shaft for movement less than 1mm there is a coating of oil on pipe from the intercooler to engine and on the intake pipe to the turbo

when removing oil cap while running there is smoke

just to make it clear there is no black smoke at all (unfortunately)

I say that because removing the turbo looks a awful job very inaccessible :(

That's odd, normally it will only be down on one cylinder not three! That does seem to suggest an injector problem but the loss of oil could be leaking turbo seals or you could have a fault in the crankcase breather system. There normally will be some oil in the air intake piping this is from the breather system.

I don't think the smoke and injector problems are related it could be though that the engine is burning oil due to loss of compression on one or more cylinders.

You really need a diesel specialist rather than a garage, they usually know what they are doing.

EGR problems shouldn't affect the oil consumption, the cause could be failure of the turbo oil seals, in fact it sounds as though its running on lubricating oil. The only other problem I can think of is failure of the crankcase breathing system causing oil vapour to be sucked into the air intake.
