Thanks mate. Im still stumped how the shim I put in would not allow it to pop/spray at all then when I disassembled and removed, reassembled back to the way they were originally and retested they were pretty much at spec. (??)If you get them all within a 5 bar zone that is pretty good. The engine will run better the closer you match them. Since your injectors have been used the internal spring has relaxed some. Not uncommon. After you get them back to specs they won't change much. Those little shims come in 30 different thicknesses so you could spend hours getting them right on the 245 bar mark. Your #1 was dead on the mark. #2 was pretty bad off the mark. The other 2 were sort of in the middle.
What about the pump timing and concerns with that given the markings on top of the pistons?
