Regarding the vac pump, setting engine to tdc helps get it back on. Taking it off, at tdc prevents the inner spring launching the pump across the engine bay.

Thanks that's what I did. I had a leaky valve cover gasket so I wanted to replace that anyways. Set the flywheel first, checked the IP notches. First time I've taken the cover off to see how this machine operates. Replaced the O ring on the pump and doesn't seem to be any noise coming from the pump. I checked the valve clearance and it was right at the minimum. Now I'm going to change the injectors to see if that helps the knocking noise. Don't think I can get 5 or 6 unless I move the IP? I will have to get the timing tools first and play around with that.

If you can get the top of the injectors off on 5 and 6. You can get a deep socket over the body of the bottom of the injector.
Otherwise I found it easier to take the top off the pump. Just make sure you note how many threads are on the idle screw and fuelling screw. There's a spring to disconnect on the throttle linkage inside too. Access is so much better after that. |

I'll give that a try this weekend. Can you still put the new one back in as one piece?

If you scribe marks very carefully on the IP and its bracket, you can loosen the four mounting bolts and rotate the pump away from the motor, get the injectors replaced, and then very carefully put the pump exactly back where it was. You need precise marks for this to go well -- rather than a scribe you may be better off giving a tap at the joint with a sharp chisel or other more exact method -- but if you get it back to where it was you'll be fine. Less risky than trying to count turns on the IP setting screws, and as you noted, disassembling the injectors to get them out doesn't help you get the new ones back in, not to mention the risk of losing the small pieces that will come free when you open the injectors up. Alternatively you can permanently solve the problem by rotating the pump further out, fixing it in that position, and retiming the position of the rear belt sprocket on the cam, but that requires the timing tools and more work.
