RE: re; oil, 11th chapter

Osman,

Usually this is indicative of worn valve guides.  In VW products,
its more likely to merely be valve stem seals -- which are considerably
less costly to replace.  They are spring-loaded rubber seals that
keep oil from dripping through the valve guides and into the combustion chamber.

The morning syndrome works as follows.  You have oil around your cam,
above the cylinders.  The valves go through bushings (called guides) into
the cylinders.  Overnight -- or after the car sits with hot (thin) oil -- 
gravity pulls 
it down through the guides.  In many VW products the rubber seals that
prevent this harden and stop sealing prematurely.  This was more of a problem in
the late 1970s, but could still show up.

A worse, but similar problem is that the brass guides themselves have worn, and
the gap between the valve stem and the guide is large enough to let oil in.  
Repairing this
requires a valve job ($$$$).

Neither is a danger to you engine, but you need to watch your oil
and keep it full.  Maybe someone has been through the repair and
can give you some tips.
