I got a spring compressor that hooks on from the outside at NAPA years
ago. Turn the knob and draw hooks up against a cap with a hole in it
that rests on the retainer.

Hey Dean.Wow, that is really strange. Any chance someone
‘liberated’ the keepers from that valve sometime in the 4 years
after the transmission failed? Here is a thread from thesamba
about the air compressor tool:

Can’t wait to hear the outcome of this.

Chuck,
Then engine wasn't making any rattling before I stopped driving
it. I only stopped because I lost 4th gear (at least) while
driving on the highway.
So if the valve isn't bent, and the valve stem is in good shape I
can replace the keepers in place. That would be a miracle. I'll
see if I can gather the parts for an 'air hold'. I have a
compression gauge perhaps the hose from that will work.
Thanks,
Dean

If the valve can be pulled back level with the other valves, it's
unlikely it is bent.
If you can get your hands on an "air hold" - an air fitting that
screws into the spark plug hole and uses air pressure to hold the
valves closed - you can compress the spring and replace the
keepers without tearing the engine apart. You can make one with an
old spark plug and a pipe nipple and a little welding or soldering
- or even JB Weld.
Turn the engine over so the valves are closed before applying
pressure - have the car in gear so the motor can't turn over. If
there's no hissing from the carb or muffler, the valve is still
seating correctly. If not, it's probably bent.
Was the engine making any rattling noises?

So imagine my surprise to discover when adjusting the valves
that one of my valve stems is below the valve spring retainer.
Its suppose to stick above that so the rocker foot can push on
it. This seems really bad. Doesn't this mean my valve has been
getting clobbered by the piston? Doesn't this mean I have to
pull the head and have it rebuilt, if possible, or replaced.
Or is this the one time when something seems bad but really isn't?
I suppose I could take off the rocker arm to see if the valve
stem is ok, if the valve spring retainer keepers are anywhere
to be seen. I don't really have much more money or time to
throw at this.
Please send me a miracle.
Oh, Its a '71 Super Beetle with about 30,000 miles on an 1915
cc engine rebuilt by Strictly Foreign (circa 2000). I was
running it with a single 34pict jetted for the larger
displacement.

p.s. to make sure my terminology makes sense,
valve stem: skinny end of valve sticking out towards the
rocker assembly.
valve spring retainer: disk shaped metal with hole in the
center for valve stem. sits on top (out board really) of the
spring
valve spring retainer keeper: This I can't see but I assume
there are two of this buggers around the valve stem that sit
in a circular groove around the end of the valve stem, they
keep the valve stem from doing what mine did, sneaking back
towards the combustion chamber.
