The diagnosis of valve stem seals is correct and the best part is it is
easy to fix. You don't have to take everything apart. You can get a
hose adapter for your compressor that screws into the spark plug hole of
the valve you want to put the umbrella seal on. Start by taking off the
rocker cover. Take the valve rocker assembly off or slacken off each
rocker as you do the valve under it. Use a spring compressor and take
off the valve springs. Under each one is the stem of the valve with an
umbrella on the newer Land Rovers or an O ring on the old types. Replace
with umbrella in every case since they work better. During the removal
of the springs etc. just pump air into the spark plug hole to keep the
valve up so you can work on it. Reverse the procedure to put everything
back together. The whole job could be done in two hours and best of all
you don't have to remove the head. Dave VE4PN P.S. If you don't have a
compressor put rope in the spark plug hole and rotate the piston up
against it to hold the valve up. I haven't done it this way but old
mechanics tell me it is very effective and cheap for the back yard
mechanic without many tools.
