Dirty or worn injectors will sometimes cause an intermittent tapping sound...you can do a search on "nailing" and get lots of information about this. Also, take a look at DieselGiant's website for the pictorals on both the diesel purge procedure and the injector nozzle replacement. I'd start by purging the car, or simply switching the injectors over as a set from the 'organ donor' and seeing if the noise persists...dirty/worn injectors could also be contributing to the low power, rough idle, and smoking problems. In my experience, a rod knock isn't intermittent, although these motors make enough noise that sometimes it's hard to tell whether a sound is consistent or not. At any rate, best of luck!
