    the smoke is dark and yer it is mostly while it is on tickover also oil is fine but its burning oil quite alot any ideas because to be honest i realy cant afford a new turbo i would rather sell it so that someone could see it upgraded but i would love to fix it could it just be the seals due to a decat? thanks

    You can get grey type of smoke when decat is fit, this is because there is less back pressure for the turbo seals and causes them to weep oil, the only way round it is to fit a oil restrictor bolt on the turbo.
