Well im all sorted & thanks mainly to MarinaBrian...He,s a canny lad
As it turned out it was more then one component at fault for the smoke
Leaky EGR...O-rings..Injectors & the EGR / Intercooler pipe..
EGR has been by-passed...All 4 injectors changed....O-rings replaced..
EGR / intercooler pipe replaced.. & a full oil & filter change...I will be taking her out today for a long run so hopefully all will be fine
