In my neck of the woods, a valve job  (machine shop work only) is $450+. I =

and seals and lapped the valves (they and the seats looked PERFECT before I=
 started) for $35, yes, that's $35.00.  But I had the tools.  The old guide=

You need :

A valve spring compressor (Mine was about $150, the on-the-car type from Sc=
heley Automotive Specialty Tools)

Valve guide seal pliers (to remove the old seals (might use something else)

Valve guide seal installer drift (about $15), there again, might use someth=

8 mm Valve guide installation (stepped) drift (about $20)

All Schley. I think that's it.  I did not have to hone the guides.

  I tried the oversize rings filed down and had terrible results.  I only g=
ot
about
30K out of a std. ring re-ring.  Of course the Rabbit's cylinder walls were
worn
quite oddly.  They weren't tapered, they were wavy.  This is where I think
a Total Seal re-ring would pay, or at least having a set of rings modified
to the TS style.  Better sealing in a marginal bore.
  Of course if your bore is worn you should really consider a rebore.  From
what a lot of your experiences, it seems that cylinders are worn more here
than in other parts of the country.  Mt. St. Helens could be the reason
for that.  There was a lot of fine abrasive floating around this state for
several years.
  As with any engine, if you do the head, do the rings and vise-versa.
Otherwise the other will tend to give out in a short time.
