Valve Clearance: Notes
- Valve clearance must be set with engine cold. Bring piston of No. 1 cylinder to TDC on ignition stroke. Align distributor rotor with timing mark on distributor housing. Check that slot in crankshaft pulley aligns with "O" mark on timing plate.
- Bring piston of No. 1 cylinder to TDC at end of exhaust stroke. Rotate crankshaft one full turn. Distributor rotor should now point 180 degrees away from housing timing mark. Slot of crankshaft pulley should again align with "O" mark on timing plate.
