I have a 5sp manual in my gas inline van...84 with a hybrid ABA/8valve head
  I don't know which one it is...yet..but mine has a bit of a howl that's
begun over the past year or so and I've been told to be 'gentle' with it
because the howl could be causing wear to the case, or something like
that...I've been saving money  to have it rebuilt soon and driving my
 other van as much as possible...'saving' wear and tear on the 5sp so as to
not cause expensive machine work during the rebuild..
  I think the 5sp is a great piece in a Vanagon, but pretty rare...I can
always find an approppriate gear for whatever I am driving over...and it
seems to really be handy both on the highway and when I am rock-crawling on
back roads...

   I'll be interested in how your rebuild turns out...keep us posted..
