Valve Clearance: Adjustments
VALVE CLEARANCE ADJUSTMENT
As the intake and exhaust valves are equipped with auto-lash adjustment mechanisms, there is no need for valve clearance adjustment. The proper
functioning of the auto-lash mechanism may be determined by checking for tappet noise. When there is tappet noise or any unusual noise, check the
auto-lash by removing and bleeding or replacing it.
