thaks for al the replies turns out the valve stem seals were done when the head gasket was done which was less that 1000 miles ago they were genuine ford stem seals have removed the plenum today and there is oil residue in there going to clean all this out and the inlet manifold poss the intercooler but there isnt any traces of oil on the pipes but just getting sick of it smoking now i took the plugs out and they are oily on every cyclinder so i can only guess that its dragging the oil from the inlet which must be related to the turbo going bang as never had one bit of smoke before hand. i dont have a crank case breather in the inlet either as its running a group a breather system
