Managed to get three of the injectors removed from the head for reconditioning but the fourth is stuck tight. Trying the usual things - moving side to sode with a spanner on the flat with lots of WD40 but can only get a small amount of movement.
Looked on various forums and one idea seems to be to make a small slide-hammer from an old unjector union nut welded to a piece of round bar with something to slide up and down on it to act as the hammer before welding a stop on the end. Just wondered if anyone has done this before and might have one lying about in the garage?
Cheers
