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.
