IMPORTANT: Exhaust valves are stellite-flashed and must not
be machined . They may only be ground in against seat.
Min:
8200/ 230 = 7,935 8204/234 = 6 ,95
IMPORTANT : Scrapping exhaust valves. The exhaust valves on turbo engines are sodium filled and must not be mixed with
ordinary scrap iron before first removing the sodium.
