1. Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

3. Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [L8, LF].)

4. Disconnect the ventilation hose. (See QUICK RELEASE CONNECTOR (EMISSION SYSTEM) REMOVAL/INSTALLATION [L8, LF].)

5. Remove the front suspension tower bar (joint). (See FRONT SUSPENSION TOWER BAR REMOVAL/INSTALLATION.)

6. Remove the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [L8, LF].)

7. Disconnect the oil control valve (OCV) connector. (With variable valve timing mechanism.)

8. Disconnect the P/S pressure switch connector.

9. Remove the ignition coils. (See IGNITION COIL REMOVAL/INSTALLATION [L8, LF].)

10. Remove the cylinder head cover. (See TIMING CHAIN REMOVAL/INSTALLATION [L8, LF].)

11. Measure the valve clearance.

  (1) Turn the crankshaft clockwise so that the No.1 piston is at TDC of the compression stroke.

  (2) Measure the valve clearance at A in the figure.
    • If the valve clearance is out of the specification, adjust it. (See VALVE CLEARANCE ADJUSTMENT [L8, LF].)
      Note
      • Make sure to note down the measured values for choosing the suitable replacement tappets.
    Valve clearance [Engine cold]
    IN: 0.22—0.28 mm {0.0087—0.0110 in}
    EX: 0.27—0.33 mm {0.0107—0.0129 in}

  (3) Turn the crankshaft 360° clockwise so that the No.4 piston is at TDC of the compression stroke.

  (4) Measure the valve clearance at B in the figure.
    • If the valve clearance is out of the specification, adjust it. (See VALVE CLEARANCE ADJUSTMENT [L8, LF].)
      Note
      • Make sure to note down the measured values for choosing the suitable replacement tappets.
