- Remove valve cover. Remove right inner fender apron extension to enable timing marks to be seen. Align crankshaft pulley timing mark with TDC mark on timing belt cover. See Figure .
- Remove distributor cap. Ensure rotor is pointing upward toward distributor hold-down bolt and to No. 1 terminal of distributor cap. If rotor is not as described, rotate crankshaft 360 degrees.
- Measure valve clearance between adjustment screw and valve stem using shim thickness gauge. Check intake valve clearance of cylinders No. 1 and 2 and exhaust valve clearance of cylinders No. 1and 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.
- Adjust valves by loosening lock nut and turning adjusting screw until clearance is as specified. Hold adjusting screw while tightening lock nut to 11.0-13.5 ft. lbs. (15-18 N.m). Recheck clearance.
