I would like to make sure I understand the different types of nozzle holders (injectors) used in the OM60X engines. From my research it seems that the 603 engine with the #16 and lower head uses the common BOSCH nozzle holder used on the 617 and VWs, and uses nozzle holders with a finer pitch thread on heads 16 and higher, correct?

It also seems that the OM 606 uses a different nozzle holder all together, yes? What type of nozzle holder does the OM 602 and OM603 use?

Thank you.
