As a general observation: valve stem oil seals are often used only on inlet valves to control the oil being drawn into the combustion chambers, and hence causing blue smoke and poor emissions. Exhaust valves don't draw oil into the combustion chamber as the chamber is at high pressure when the valve is open.
