Handling and disposal of sodium-filled exhaust valves requires special care and consideration. Under conditions such as breakage with subsequent contact with water, metal sodium which lines the inner portion of exhaust valve will react violently, forming sodium hydroxide and hydrogen which may result in an explosion. Sodium-filled exhaust valve is identified on the top of its stem as shown in illustration.

Strike the valve face end with a hammer, separating it into two pieces.
Carefully place the already cut (serrated) valves into the water one-at-a-time using a set of large tweezers and quickly move away at least 2.7 m (9 ft).
However, no more than 8 valves should be placed in the same 10 (2-5/8 US gal, 2-1/4 lmp gal) amount of water. The complete chemical reaction may take as long as 4 to 5 hours.
Remove the valves using a set of large tweezers after the chemical reaction has stopped. Afterwards, valves can be disposed as ordinary scrap.

Diagnosis Description
This system is an on board diagnostic system that records exhaust
emission-related diagnostic information
and detects a sensors/actuator-related malfunction. A malfunction is indicated
by the malfunction indicator
lamp (MIL) and stored in ECU memory as a DTC. The diagnos ...
