Drew,
Hi.  I've heard of more people having problems with the core and gasket than
the valve itself.  But since you're back there, you may want to do it all...
the gasket 861 819 297.  The valve is 867 819 809B and sells for about 45
bucks and the core is 867 819 121A and sells for about 70.  Beats doing it
in the cold this winter.
Cheers,

Jim
91 Syncro Adventurewagon, new core and gasket last winter.
