Valve Clearance: Adjustments

ADJUSTING VALVE CLEARANCE
As the intake and exhaust valves are equipped with auto-lash adjustment mechanisms, there is no need to adjust the valve clearance. The proper function of the auto-lash mechanism may be determined by checking for tappet noise. When there is tappet noise or any unusual noise, first check the engine oil pressure. If the engine oil pressure is okay, check the auto-lash by removing and bleeding or replacing it.
