CAMSHAFT

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

Note

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

Prick a hole in the tape covering the oil hole as shown in the illustration.
*a Protective Tape

Apply approximately 200 kPa (2.0 kgf/cm², 29 psi) of air pressure to the hole to release the lock pin.
Note
- If air leaks out, reattach the adhesive tape.
- Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.
Using a screwdriver with its tip wrapped with protective tape, forcibly turn the camshaft timing exhaust gear assembly in the retard direction (clockwise).
Note
- Be sure to keep the camshaft timing exhaust gear assembly in the retard direction using a screwdriver. If the camshaft timing exhaust gear assembly is released, it will return to the most advanced position automatically due to the force from the spring.
- Do not damage the camshaft timing exhaust gear assembly.
Turn the camshaft timing exhaust gear assembly within its movable range (24 to 26°) 2 or 3 times, but do not turn it to the most retarded position. Make sure that the camshaft timing exhaust gear assembly turns smoothly.
Remove the adhesive tape from the camshaft bearing cap.
