Valve Clearance: Notes

NOTE: Crankshaft pulley has 2 notches. When cylinder No. 1 is at TDC, upper notch will align with "O" on timing marker and lower notch will be 150 degrees counterclockwise from upper notch. Second notch is TDC for cylinder No. 6 when aligned with "O" on timing marker.

Adjust valves with engine cold. Rotate crankshaft so cylinder No. 1 is at TDC of ignition stroke (both rocker arms for cylinder No. 1 have clearance). See VALVE CLEARANCE ADJUSTMENT SEQUENCE table and adjust valves.
Now, rotate crankshaft until second pulley notch aligns with "O" on timing marker. This will set cylinder No. 1 at TDC of exhaust stroke (rocker arms for cylinder No. 1 pivot indicating no clearance). Adjust remaining valves.
