Not sure what happened, when the injectors were pulled for the initial rebuild, two were completely blown (held no pressure) two were off spec (85, 90 bar) and one was about 129. Not completely familiar with the shim/pressure relationship, but the #5 injector may have had a shim settle more than the others?

Of course now I am keeping a close ear for the other four and if any of them start to nail I know where to start first.
