By removing the injector wiring one at a time I found the number 5 injector to be bad, by disconnecting the number 5 wiring the knocking stopped,apparently it was pumping excess fuel into that cylinder and pounding it, that is what was making the knocking noise and the excessive carbon particles coming out of the exhaust. As I had no signs of the black death around the injector I didn't even need to clean the injector bore, the 5th cylinder is to far back to work on anyway. All I did was replace the one injector with a rebuilt one and a new injector bolt and seal and the engine has run fine for 6 months now. I was able to loosen the injector by loosing the injector bolt a bit and then starting the engine.

Wow! I can’t believe that’s the sound from a bad injector! Thank you for sharing this info with us! How’s the van holding up with the rebuilt injector? Have you had any more issues?

So I have the same knock on mine. Pulled the wiring off it stopped. However I've changed the injector with a new bosche on 5 and glow plugs on all cylinders. Still there. Come on at stop signs or idles. Not as loud but still on 5

Hi Michael that was a bad injector? Making that sound? Mine is doing something similar but definitely not as loud
