- 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. Adjust valve clearance if not within specification. See VALVE CLEARANCE SPECIFICATIONS table.
- 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.
- Reverse removal procedure to install remaining components.
