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.
