Valve Clearance: Adjustments

Valves should be adjusted cold.

1. Set No. 1 piston at top dead center with mark on camshaft pulley at top and TDC groove on back of pulley aligning with cylinder head surface. Also, distributor rotor should point toward No. 1. plug wire terminal
2. Loosen locknut and turn adjustment screw until feeler slides back and forth with slight amount of drag. Then tighten intake and exhaust valve locknut to specifications:

Intake 0.009-0.011 inches
Exhaust 0.011-0.013 inches

3. Rotate crankshaft 180° counterclockwise. TDC groove on camshaft pulley should align with index mark on timing belt cover, and distributor rotor should point toward No. 3. Check clearance on No. 3 cylinder and adjust as in step 2.
4. Rotate crankshaft 180° counterclockwise. TDC groove should align with cylinder head surface, and distributor rotor should point toward No. 4. Check clearance on No. 4 cylinder and adjust as in step 2.
5. Rotate crankshaft 180 degrees counterclockwise. Mark on pulley should be visible, and distributor rotor should point toward No. 2. Check clearance on No. 2 cylinder and adjust as in step 2.
