I suspect you mean valve guide SEALS,
not valve guides.
As I posted a couple of weeks ago ...
when inline 8 valve 1.8's where 'new' in Rabbits .....
they were known for using oil past the valve guide seals.
That motivated VW to put a sticker on the gas cap door saying to check the
oil lever every time you gas up, as it was a chronic problem at the time.
Vavle seals can be replaced with the head on the engine, engine in the van.
You position a cylinder to TDC on compressione.........then pressurize that
cylinder with compressed air through the spark plug hole...
That way you can compress the vavle srping, remove the keepers, then spring,
then get at the valve guide seals.
the intake ones are the main ones to be concered about I beleive.
3 times the post says 'guides' ..........of course the head has to be off
to replace 'valve guides.' ...a bronze like metal part the valve slides in.
And the valve guide Seals sit on top of the valve guide.
but I know what you meant Don !
shame about that guy's motor home sinking into the sand and ocean. Bet he
never does that again !
He shoulda had a vanagon ..........mighta been able to pull one of those out
!
and if syncro ...........hey .........it sure SHOULD have been able to
self-rescue.
