        *c

        Adhesive Tape

        Clean the VVT oil hole on the intake side of the camshaft bearing cap, and completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.

        Note:

        Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.

      2. Prick a hole in the adhesive tape sealing the oil hole as shown in the illustration. (Procedure A)

      3. A198702

        Apply approximately 150 kPa (1.5 kgf/cm2, 22 psi) of air pressure to the hole pricked in procedure A to release the lock pin.

        Note:
        • If air leaks out, reattach adhesive tape.

        • Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.

        • Do not lock the camshaft timing gear assembly. If it is locked, release the lock pin again.

        Tip:
        • The camshaft timing gear assembly may be turned in the advance direction without applying any force.

        • If enough air pressure cannot be applied because of air leakage from the port, releasing the lock pin may be difficult.

      4. Remove the adhesive tape from the camshaft bearing cap.
