    NOTE: Be sure to cover the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.
  1. After cleaning and degreasing the VVT oil hole on the intake side of the No. 1 camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.
  2. Prick a hole in the tape covering the oil hole as shown in the illustration. (Procedure A)

    NOTE:
    • 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.
    • If air leaks out, reattach the adhesive tape.
    • Cover the oil hole with a shop rag or 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.
  3. Apply approximately 150 kPa (22 psi) of air pressure to the hole pricked in procedure A to release the lock pin.
  4. Remove the adhesive tape from the No. 1 camshaft bearing cap.
