Valve Clearance Adjustment: 8-Valve
- Remove rocker cover. Rotate crankshaft until TDC mark of timing belt cover is in line with timing mark on crankshaft pulley with cylinder No. 1 at TDC on compression stroke.
- Remove distributor cap and ensure rotor is pointed upward at distributor hold-down bolt and to No. 1 terminal of distributor cap. If not correctly oriented, rotate crankshaft 360 degrees.
- Measure clearance between adjustment screw and valve stem using thickness gauge. Check intake valve clearance of cylinders No. 1 and 2 and exhaust valve clearance of cylinders No. 1 and 3.
- 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. Ensure clearance is within specification. See VALVE CLEARANCE SPECIFICATIONS .
- If clearance adjustment is necessary, loosen lock nut and turn adjusting screw. After adjusting clearance, tighten adjusting screw lock nut to 11-14 ft. lbs. (15-19 N.m). Recheck valve clearance.
