Valve stem seals
I have an 84 with about 120,000 miles on it and its now time to do the Valve stem seals. Now I'm planning on doing the compressed air through the spark plug method. Can anyone give me pointers on how best to do this so I dont drop a valve by accident?

If I remember this method correctly, you want to do it when both valves are closed, in the order of the firing order. The thing is, is if you have enough LP air pressure going in there, it should hold the valve up. Personally, I would just go ahead and pull the heads and recondition them, since I'm sure the combustion chamber and valves probably need a good cleaning.

On my engines, I move the piston to the bottom, stuff thin plastic rope in there until it is about full, then push the piston up against the rope.
