Does a diesel engine have a positive crankshaft ventilation valve?
No, the crankcase ventilation systems employed on diesels are not PCV (Positive Crankcase Ventilation) systems. They are CCV (Closed Crankcase Ventilation) systems. Diesels do not produce sufficient vacuum for a PCV system. They use only a crankcase breather which is vented to the filtered side of the intake ducting. The engine can "breathe" both in and out via the breather cap. The round black thing on the TDI valve cover is a breather cap.
