I didn't ask the question but I suspect as John's found it's a Positive Crankcase Ventilation valve.

The Positive Crankcase Ventilation valve, or PCV valve, is a one-way valve that ensures continual evacuation of gases from inside a gasoline internal combustion engine's crankcase.

I know petrols have to have them and they use the manifold vacuum to do the "Positive Ventilation".
But not sure about diesels (esp turbos) as they don't have manifold vacuum to do the "Positive Ventilation" bit.

........but they do have a vacuum pump..... There must be some form of crankcase breathing system otherwise the oil seals would pop - I'll have a squint at lushprojects pages sometime.

I've never seen a diesel vacuum pump that connects to any sort of PCV valve and I don't think I'd like to see one that has been connected to one and sucking on all that goo for any length of time.
The crankcase has to have a breather that's obvious, but I'm not sure it vents to the inlet system anywhere or how.
