Caution
•
••
• Variable valve timing actuator can not be disassembled it is a precision unit.
1. Disconnect the negative battery cable.
2. Remove the plug hole plate.
3. Remove the high-tension lead.
4. Remove the oil control valve connector.
5. Remove the ventilation hose.
6. Remove the cylinder head cover.
7. Confirm that notch of the rotor and bump of the
cover at the variable valve timing actuator are
aligned and fitted.
• If the notch and the bump are not aligned,
turn the crankshaft clockwise two rotations.
Verify that the bump and the notch are
aligned.
• If the bump and notch are still not aligned,
replace the variable valve timing actuator.
• If, when turning the crankshaft, there is a
hitting noise from the variable valve timing
actuator each time the cam passes the fully
lifted position, it means that the actuator is not
secured. Replace the actuator.
8. Install the cylinder head cover. (See B17 Cylinder Head Cover Installation Note.)
