Blue Smoke

Morning all...



Been having a slight blue smoke issue now for some weeks and could do with your opinions..



On start up I slowly get a slight blue smoke coming from the zaust and while I leave it ticking over it's mainly constant and also stinks of Diesel (De - Catted) when I pull off I leave a nice cloud and then it goes away..till I pull up and it slowly re appears ??



When I get going and give it some welly I get the nice standard black cloud!!



I have SDi's fitted, boost at 19 psi, de - cat and straight thru zaust...my thoughts are..



1. Valve stem oil seals (not read much on here re this problem)



2. Maybe the Turbo (but got no performance loss)



I service regular (6 - 8k) oil filter fuel filter air etc.



Any ideas on this one please??



P.s. 113500 on the clock and 54 plate (never have to put in oil between changes ?? )
