[Fot] Oil collecting on TR6 valve cover

[sherry robyn]

Just wondered if anyone had experienced this and might know where this oil is
coming from.  Oil collects on the outside lip of the valve cover at the back
of 
the engine.  I have a new cap on the valve cover and the hose exit on the
side 
of the valve cover is plumbed to a clear jar that collects no oil at all
ever.  
Any thoughts would be appreciated.  Jim
