Depends on the quality of the gasket you start with.  The unbranded ones I've
gotten from the local VW parts haus came without the benefit of a package and
made by God only knows.  They didn't hold up too well.  They ones I've gotten
which come in a cardboard box from Fel-Pro last for damn near ever.  I've
seen somewhere that silicone valve cover gaskets are available; those might be as
good as it gets, but at a price.
