ive changed the injectors, the sump gasket, rocker head gasket, oil filter and the oil, what else could be making it smoke, it only smokes on acceleration
on a more serious note have you tryed to advance or retard the fuel pump there are 2 or 3 slotted bolts at the base of the pump loosen them off but dont remove and twist the pump. though a certain amount of smoke seems to be the norm on these engines as they are not very refined and a lot of the smoke is just unburnt fuel going out the exhaust
