Face it, it's already bad.  Procrastination could leave you with nothing to
rebuild or even use as a core to trade in.  Park it or fix it, those are
your only good choices. BTDT.

Good luck!

Thanks Larry!

Sadly, when I checked my van the other day after going up a somewhat serious
hill and I saw some small amount of bubbling in the tank behind the license
plate when it was idling - so I suspect there are combustion
gasses coming through.  :/   I'd like to do the sniffer test again.  Is
there any chance this could be coming from anything natural - eg, like
steam/water vapour from the coolant?   Engine was probably on for about
15 minutes in total - warm enough to get up to full operating temperature,
but not for any length of time.

I'm torn on what to do.  I really don't have the time on my hands to do a
full engine removal and disassembly ala
http://www.thesamba.com/vw/forum/viewtopic.php?t=286798 - so do I keep
driving it gently with this knowledge and wait until it gets so bad the
engine overheats?...   I suspect it'll get worse over time and force me
to fix it.
