The engine oil is drawn from the oil pan and routed to the camshaft oil ducts via the engine oil circuit before passing from there to the VCT oil control solenoid and to the locking pin. This releases the locking pin and separates the positive engagement between the camshaft pulley and the rotor. When the control unit is being retarded, the chamber (b) fills with engine oil. The rotor turns clockwise because of the oil pressure in the chamber (b). The engine oil returning from the chamber (a) flows via the oil return duct (D) to the VCT oil control solenoid and from there back into the oil pan.

Timing retard

When the VCT control unit is being advanced, the chamber (a) fills with engine oil. The rotor turns counter-clockwise because of the oil pressure in the chamber (a). This completes the advance adjustment. The engine oil returning from the chamber (b) flows via the oil return duct (D) to the VCT oil control solenoid and from there back into the oil pan.
