8v Valve stem seals

Hi list,
    I'm trying to find information on a factory defect VW had in the late 
'70's, it was on the 8v in '78 I think.
    As I recall, the problem was the factory valve stem seals were too good, 
didn't allow any lubrication at all to the valve guides. So the guides 
failed early. There was a quiet "recall", nothing dramatic.
    For a while there was a "new" good type seal, and an "old" bad seal.
    Anybody else know anything about this issue?
