Valve Clearance
- Remove valve cover. Remove right side under engine splash shield. Remove air cleaner cover to enable viewing of timing marks. Align crankshaft pulley timing mark with TDC mark. See Fig 1 . Remove distributor cap. Ensure rotor is pointing to No. 1 terminal of distributor cap.
- Check the intake valve clearance of cylinders No. 1 and 2 and the exhaust valve clearance of cylinders No. 1 and 3. See the VALVE CLEARANCE SPECIFICATIONS table. Turn crankshaft one complete revolution (360 degrees). Check intake valve clearance of cylinders No. 3 and 4 and exhaust valve clearance of cylinders No. 2 and 4.
- Measure valve clearance between cam lobe and rocker using feeler gauge. Adjust valves by loosening lock nut and turning adjusting screw until clearance is as specified. Hold adjusting screw while tightening lock nut to 96-108 INCH lbs. (10-13 N.m). Recheck clearance.
