Hi, all,

This was discussed once (as far as I could find) in the archive, last
August.  The sole response to the described problem was "look under
the engine ... if it's sufficient to put an oily film on your back
hatch, the cause will be obvious".

Except ... it's not obvious!  Not to us, nor to the VW repair shop
where we take our Vanagon.  And the repair shop has so far not steered
us wrong. (Our shop-supplied engine has not yet done 10,000 miles. And
it isn't a re-conditioned engine ... it's a new VW engine.)

The best suggestion the repair shop could offer was that we'd been on
newly-oiled roads.  That just doesn't fit.

So I wonder ... has anyone else had this happen, and if so what were
the suggestions and (hopefully) fix for the problem?

Just to make the question more interesting, we're off to San Felipe,
Baja Norte, Mexico, next weekend - filmy hatch or not!!!  I (the more
adventure-conservative of us two) have decided that if I'm in an older
vehicle that needs attention, I'd rather have that happen in Baja than
in the US.  Those folx know how to cherish good, old vehicles!
