Valve Clearance: Adjustments

Fig. 2 Aligning crankshaft pulley:

1. Remove air cleaner and cylinder head cover.
2. Turn crankshaft clockwise and align timing notch on crankshaft pulley with 0 mark on timing tab, Fig. 2.

Fig. 3 Distributor rotor at TDC position:

3. Remove distributor cap. Engine is at TDC when distributor rotor is positioned as shown in Fig. 3. If engine is not at TDC, turn crankshaft 360 degrees so timing notch is at 0 mark again.

Fig. 4 Adjusting valve lash:

4. Using feeler gauge, measure No. 1 cylinder intake and exhaust valve clearances at 1 in Fig. 4.
5. Adjust valve lash, if necessary, by turning adjusting screw after loosening locknut, Fig. 4. After adjustment, tighten locknut to specified torque.

Fig. 5 Crankshaft pulley alignment w/left side timing belt cover bolt:

6. After checking No. 1 cylinder, turn crankshaft 240 degrees clockwise and align timing notch on pulley with left mounting bolt of timing belt cover, Fig. 5. Check and, if necessary, adjust intake and exhaust valves of No. 3 cylinder.

Fig. 6 Crankshaft pulley alignment w/right side timing belt cover bolt:

7. Rotate crankshaft 240 degrees clockwise from left mounting bolt, and align timing notch with right mounting bolt as shown in Fig. 6. Then, check and, if necessary, adjust intake and exhaust valves of No. 2 cylinder.
8. After checking and adjusting valves, install distributor cap, cylinder head cover and air cleaner.
