dephaser solenoid noise

[Rob669]

My Ph1 has developed a noise under the dephaser solenoid switch. It doesn't stop if I unplug it. It sounds like a pigeon at rest to me! I'm wondering if it might be cam related? I took the top mount off and it isn't the dephaser, it's something under the solenoid if not the valve itself.

Any ideas please?

The thinking is that this could be either one of the timing belt rollers that's worked lose or cam journal wear. Any expert views? The noise is coming from the area under the solenoid switch.
