Continuous Variable Valve Timing (CVVT) Assembly

  1. Inspect the exhaust CVVT for smooth rotation.
    1. Clamp the camshaft using a vise. Be careful not to damage the cam lobes and journals in the vise.
    2. Check that the exhaust CVVT is locked by turning it clockwise or counterclockwise. It must not rotate.
    3. Intake CVVT: Seal one of the two advance holes in the camshaft journal with tape.

      Exhaust CVVT: Seal one of the two retard holes in the camshaft journal with tape.

    4. Exhaust CVVT: Apply approx. 150 kPa (1.5 kgf/cm2 , 21 psi) of compressed air into the unsealed retard hole to release the lock.

      Information 

      Cover the oil paths with a piece of cloth when applying compressed air to prevent oil from spraying.

    5. With compressed air applied, rotate the exhaust CVVT into the retard direction (clockwise) and check that the CVVT turns smoothly.
