Check

Remove the VVT solenoid. 
Blow compressed air into the oil feed hole (2). Air should come out through the B port (1)
If the duct seems to be blocked, go to the cleaning step.

Connect current to the solenoid.
The solenoid should click. It may be easier to hear the click with the solenoid in your hand.
Blow compressed air into the oil feed hole (2). Air should come out through the A port (3). If the piston jams or the solenoid does not work, the direction
of flow will not change. If the duct seems to be blocked, go to the cleaning step.
