Another common leak that you should ckeck is the distributor drive
O-ring.  I had oil on that same big screw and after replacing damn near
every seal and gasket in the vicinity, I discovered the oil was actually
coming from way up top beneath the distributor.  This is an extremely
easy and cheap fix, and an awful lot of vanagons leak oil there.  Take
off the distributor cap, then loosen the distributor and pull it out.
You should see a black O ring on the drive shaft.  If the ring is hard
and flat, replace it.
