Do you have a reference for that procedure (I'd like to see more about the timer)? > I believe you're on the wrong track.

The opinion on it being timing-related did not come from solely from me, it is also from two mechanics with extensive diesel background, who I had listen to it. > This can be caused by poor injection pressure (either the delivery valve > seals or the condition of the injectors can be responsible for this), > poor spray pattern, or poor conditions inside the prechamber (debris > inside or the prechamber is cracked). The injection pressure was supposedly checked at the shop. The injectors were just cleaned and tested, and I already tested a different one in the 'problem' cylinder just in case the rebuilder goofed on one. IF it were debris, I would expect to not only hear it as a transient noise on the application of load, which is all it is. It is not present otherwise. It isn't at all a metallic or mechanical noise, it's more like a SNAP. TKS Mac
