Valve Clearance Adjustment
NOTE:
Valve clearance can be adjusted with engine cold or hot.
- Disconnect negative battery cable. Remove air cleaner assembly and valve cover. Rotate crankshaft until cylinder No. 1 is at TDC of compression stroke. Ensure timing "V" mark on crankshaft pulley aligns with "0" mark on timing belt cover.
- Remove distributor cap. Ensure rotor aligns with cylinder No. 1 distributor terminal. If rotor is not aligned with cylinder No. 1 distributor terminal, rotate crankshaft pulley clockwise 360 degrees.
- Measure clearance between adjustment screw and valve stem using a feeler gauge. Check clearance of intake valve(s) of cylinders No. 1 and 2, and exhaust valve(s) of cylinders No. 1 and 3.
- Rotate crankshaft clockwise 360 degrees. Check clearance of intake valve(s) of cylinders No. 3 and 4, and exhaust valve(s) of cylinders No. 2 and 4.
- Adjust valve clearance if not within specification. See VALVE CLEARANCE SPECIFICATIONS . Adjust clearance by loosening adjusting screw lock nut and rotating adjusting screw. Tighten adjusting screw lock nut to 13 ft. lbs. (18 N.m) while holding adjusting screw.
