Eric,

Here's a quick, temporary fix. Remove the oil filter. You will notice
on the oil cooler unit a large, thin nut that holds the oil cooler
into place. Tighten that nut a bit, that should snug up the oil
cooler to the block so that you are able to drive for a while without
dropping oil. VW's service procedures for the Vanagon recommend that
their service techs tighten up this nut at every oil filter replacement.
