Valve: Application and ID

Exhaust Valve Identification.






DESCRIPTION
Two types of exhaust valves may be installed: Standard valves (A in illustration) or carbon break valves (B in illustration).

IDENTIFYING
Carbon break valves may be identified by the machined profile C on the valve stem.

REPLACING
To prevent exhaust valves from sticking, standard exhaust valves should be replaced with carbon break valves during engine overhaul.
