To change any valve stem seal, you need to remove everything above the valve itself, including the spring. On most engines it is possible to do with the heads on the engine depending upon how much room you have. To keep the valve from falling into the cylinder, I use a length of 1/4" cotton rope (like you hang clothes on). Insert it into the cylinder when near TDC and gently turn the engine till it's pressing on the valve, Then when removing the spring the rope will suport the valve. There is a spring removal tool that looks like a larger version of a top terminal battery cable remover. You can use that to take spring off. DO NOT TURN THE ENGINE 'TILL ROPE HAS BEEN REMOVED. TURN ENGINE BACK SLIGHTLY TO RELEASE IT. If you find that any valve stems rock back and forth more than a very tiny bit, remove the heads and have the guides replaced. If your repair requires cams to be removed, be sure you have instructions to re set cam positions (same as timing chain replacement) Some people retain the valve with compressed air, but if the air flow stops or you press down on the valve it can relaease and fall.
Good luck...be sure that there is a reason for doing this work and that you don't have worn rings.

SOURCE: replace valve stem oil seals
Make up an airline fitting that will screw into spark plug hole, or buy from autoparts , or tools supply place. You put compressed air in cylinder while changing, which holds valves in place.

This problem is usually the result of worn rings but since you already did that, then check the passage that the PCV valve is connected to. It might be clogged, causing a restriction. If that isn't it, then drill a hole at least a quarter inch in size in the top of an old valve cover filler cap and install it. Drive the vehicle and see if things improve. If they do, then check to make sure that you have the correct PCV valve installed.
