Hi,

I am trying to fix a mega oil leak on an '86 Vanagon for a friend.  Although
we are unable to see the leak, a local VW rebuilder / machinist told me to
"remove the water pump belt and I will see it".  

Apparently the leak is from one of two possible places, but most likely an
"o" ring-type gasket that can be replaced without removing the engine. If
this is the case then which "O" ring / gasket should I be looking for?

Has anyone had this problem before and fixed their leak ??  What should we
be looking for once the "water pump belt" comes off?  Any Bentley reference
pages to help me out??

Thanks,
Shawn
