Valve Clearance

CAUTION: Valve clearance should be checked with engine cold.

Disconnect negative battery cable. Remove valve cover and gaskets. Rotate crankshaft until No. 1 cylinder is at TDC of compression stroke. Ensure timing mark on crankshaft pulley aligns with zero mark on timing belt cover.
Valves on No. 1 cylinder should have clearance and be closed. If valves on No. 1 cylinder are not closed, rotate crankshaft one revolution (360 degrees).

Using feeler gauge, measure clearance between rocker arm and valve stem on intake valves on cylinders No. 1 and 2, and exhaust valves on cylinders No. 1 and 3. Valve clearance must be adjusted if not within specification. See VALVE CLEARANCE SPECIFICATIONS table.

VALVE CLEARANCE SPECIFICATIONS

Application

Clearance In. (mm)

Intake

⁽¹⁾ .005-.007 (.13-.18)

Exhaust

⁽¹⁾ .006-.008 (.15-.20)

⁽¹⁾	Adjust valve clearance with engine cold.

Adjust valves by loosening lock nut and turning adjustment screw until correct clearance is obtained. Hold adjusting screw while tightening lock nut and recheck clearance.
Rotate crankshaft one revolution (360 degrees). Check intake valve clearance on cylinders No. 3 and 4, and exhaust valves on cylinders No. 2 and 4. Valve clearance must be adjusted if not within specification. See VALVE CLEARANCE SPECIFICATIONS table.
To install remaining components, reverse removal procedure.
