Valve Clearance: Adjustments

Camshaft Timing Marks:

NOTE: 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.

Valve Adjustment:

2. Loosen intake/exhaust valve rocker locknut and turn adjustment screw until feeler slides back and forth with slight amount of drag. Clearance should be:

Intake: 0.18-0.22 mm (0.007-0.009 in)
Exhaust: 0.23-0.27 mm (0.009-0.011 in)

Tighten locknut to 20Nm (14 ft. lbs) when done.
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.
