These engines have a design fault where a little diesel drips down onto the cylinders when stopped. Then on start up in cold conditions the blue smoke is very prominent for a short while. Apparently there is a fix for this which i have not done. I would run the engine under load for a while and give it some welly after it has properly run in

We are talking about the fresh water pump at the front of the engine, not the raw water pump at the rear. Injectors don’t drip when stopped, if they do, the nozzles need replacing. Skilled specialists can reseat the needles in the nozzles using jewellers rouge or Brasso but realistically changing them is the best option.
As I have said before, the only way to get the correct ones is to remove the old ones and get the part number off them. You need to dismantle the injectors to do this. It’s printed on the base of the nozzle.
