Freelander 1 Quick question about TD4 updated breather...

Just piecing together the top end of the engine after a local garage stripped it and abandoned the workscope on it, and looking at the Crank Case Breather I was wondering what, if anything goes onto the little nipple ontop of the PCV? And if it is a hose, where is that hose mand to go to?

eant to go to?

Nothing goes on that. It's blocked.

A locating lug fits onto it from the injector loom as it the photo below showed by yellow dots.
