Crankcase vent hose, '87 Scirocco

I'm trying to find a replacement for the crankcase ventilation hose (pipe?)
for my '87 16V Scirocco.

VW says they haven't got it and can't get it. Same from a couple of local
supply places.

This goes from the vent on the front of the engine, to the intake air
housing over towards the right. However, it's also got a small tap that
goes to the intake manifold above the oil filter about level with the head.

There's a picture he http://home.comcast.net/~paralyn/Misc/CVPIPE.JPG

The picture is from my other 16V, the pipe here is fine. The damaged one is
open over near the crankcase vent.
