Thanks, Jonathan.  I'm not familiar with what came on air cooled
Vanagons but I am familiar with the breather towers on wasserboxers.  By
your description, they are different.  First, the only way to get the
top off the ones for wasserboxers is with a saw.  The top is molded in
place.

Anyway, on mine, there is never any restriction from the crankcase end
to the hose to the throttle body.  I can suck or blow and the air path
is straight through.  Obviously, my diaphragm is shot so I'm ordering a
new tower.
