Vanagon List is not the best place to look for help with inline VW motors.
On here, not many know or care about them as a Vanagon transplant
alternative.  There's a few, but mostly you'll get "downer comments" and
opinions that inline vw motors aren't worthy and will cost the same as a
Subaru or Ford to stick into a Vanagon.

I suggest your area Craig's List.  I almost always find them in the
Northwest, very common, very cheap.  $300 is the most I would ever give for
a decent  ABA motor.  VW Vortex is a web Forum with lots of inline
classifieds and info on the vw sedans.  Yahoo group for Vanagon Inline,
too.  I'm on an Android and I don't know how to Link that, but we're kinder
and gentler over there.  Tucson and Phoenix should have a few Jettas
listed...
