I just lift the valve off the seat some, line a quarter inch, or even a half
inch and wiggle it left and right and see how far it moves to check guide
wear.  A sixteenth of an inch would be pretty 'too much.' ........or at
least ' really getting pretty loose.' 
The exhaust guides wear more than the intakes usually. 

Valve seals mount to the top of the valve guide basically and the valve stem
slides in them.

Subject: Re: Exhaust & intake valve instalation question

Denis,
only one of my heads had the seal washers on the intake valve, but I could
not find the part number on ETKA so I assumed that they were not OE.  Do
you have a part number for those? None of my other 5 heads had them.  Also,
what keeps it in place on the valve stem?

To check for the valve guide wear, do I just push the valve stem until the
enc of teh stem it is flush with the guide and measure the movement of the
valve "head"?  Any suggestions/tricks on how to measure that movement
without the VW tool shown in the Bentley?  I have that dial measuring tool
but I do not have the attachement to mount it to the head. Thanks
