VALVE CLEARANCE INSPECTION [MZR-CD (RF Turbo)]

1. Remove the engine cover. (See TIMING BELT REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2. Remove the timing belt cover bolt as shown.

3. Remove the cylinder head cover. (See CYLINDER HEAD GASKET REPLACEMENT [MZR-CD (RF Turbo)].)

4. Turn the crankshaft and align the timing mark so that the piston of the No.1 or No.4 cylinder is at TDC of compression.

5. Measure valve clearances A with the No.1 cylinder at TDC of compression, and those of B with the No.4 cylinder at TDC of compression.

• If the valve clearance is not within the specification, adjust the valves. (See VALVE CLEARANCE ADJUSTMENT [MZR-CD (RF Turbo)].)

IN: 0.09-0.21 mm {0.004-0.008 in}

EX: 0.29-0.41 mm {0.012-0.016 in}

6. Turn the crankshaft one full turn and measure the remaining valve clearances.

• Adjust if necessary. (See VALVE CLEARANCE ADJUSTMENT [MZR-CD (RF Turbo)].)
