Valve Clearance: (1.6L)

  1. 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.
  2. 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).
  3. 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.
  4. 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.
  5. 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.
  6. Apply sealant to No. 1 and 5 camshaft bearing cap-to-valve cover areas before installing valve cover and gasket. Reverse removal procedure to install remaining components.
