I would try swapping the injector now in 3 into another pot before I messed with the delivery valve. On the OM617 a dirty injector that displays problems when the engine is warmed up is more common than a pump issue, to cause this.
Just get some new heat shields (washers) and swap injectors between cylinders, and see if the miss follows the injector.
