1986 e28 m20 528e - where does valve cover breather hose terminate?

[blockerb]

I've done some searching but can't find an answer. My valve cover has an outlet for a breather hose, but I can' find out where it's supposed to terminate. Part number on realoem is 11151278804. ECS Tuning calls it a crankcase ventilation hose.

Any ideas where this it supposed to conect?

Thanks.
