Diesel pooling in and around injector well on 1 pair of injectors. The top of these injectors and around seem to be greasy and covered in what is most likely diesel. I can't see any leakage when engine is idling so i assume it's only occurring under load. Injectors have been refurbed by previous owner. 
im hoping its just the copper washer but does anyone know if this is the case or is it something worse? 
thanks

Hi when injectors are renewed unless you are really lucky and dont go mad tightening the feed pipes up you normally need to use new feed pipes tightened to the correct torque, diesel has what's known as capillary action and will seep through the smallest gap, you can try just giving the unions just the smallest tweak to see if that solves the problem but if whoever fitted the injectors has tightened the unions very tight you run the risk of snapping something or increasing the leak where the pipe union seal has become deformed.
