Incidentally, Mark. Would you know what special size socket I'd need to remove the injectors? I'm not sure if it could be a lose olive, leak off pipe or copper washer, but their's a trail of diesel down the side of the engine that drips on the ground. I'll double check when getting the engine up to temp with manifold off.
 
This is the one I got, with the window for number 4 injector.

I'm in luck as it's the 5th injector. I replaced the leak off pipes a year or so back but I'll check them again.
PM me with an Email address and I will send you my steel rule timing info.
Depends what you used for the leak off pipes the first stuff I tried only lasted a year. Got the Gates reinforced stuff on there now.
 
Cheers, Datatek. I've already got a copy from you thanks. I've got to put some masking tape on my steel ruler with 16th of an inch increments as it only has 16ths on the first three inches of the ruler.
