Vahid,
I am 90% sure that the '80 Vanagon did not have a PCV valve.  Certainly
the federal models did not (I've never seen an air-cooled VW engine with
a PCV valve) but you never know with the California models.  On the
federal models at least there is merely a breather box on the top center
of the engine, which is connected by a hose to the S-shaped boot before
the throttle valve.  It's a straight crankcase vent, no valve.
