so does this mean I dont have a oil pressure issue u think? or can lack of oil still cause this

Having a quick look at this:

Oil control valve: The control unit then actuates changes through an oil control valve positioned at each intake camshaft sprocket. The oil control valve uses oil pressure from the engine to advance and retard the intake camshafts via the AVCS actuator.
Actuator: Mounted in the chain- or belt-driven drive sprocket, the actuator is fitted directly to the camshaft. Chambers in the actuator allow oil pressure to advance or retard it within the timing-belt sprocket. The oil fills the chambers and pushes against three lobes to turn the actuator and the camshaft on its axis.

Having not looked into the system in detail I can't comment more, but there are only a few components that control the system. Is this the original cam systems? I'm sure I've read that some issues have occurred using older/newer components to the original ECU.
