VE internal cam actuators

[Woodsman444]

Seeking information about what Holden's call cam shaft actuators,my idea of actuators is not like theirs, they sit on the end of the cam behind the phase plate. On bank two of my engine they tell me the two round gear cogs (not sure what else to call them) that run one of my chains they say needs replacing, The price for this job will be $3,400.00 which seems bloody expensive to me, I have added the pics to this post if my description is too vauge.

Those are the VVT (Variable Valve Timing) actuators. Looks a bit late to be getting quotes since the timing cover is off.

My question is is $3,400 sound right? I'am told one is $340 the other $400 or so it seems a lot of money just to replace them when Holden's are not certain they are the problem.

Sounds like they want to do the chains as well.

That is at the high end for this job, but it looks like they have you by the short and curleys ( can't really take it home) Looks like it has a bit of oil sludging near the chains.

Thanks
Can you tell me if the VVT cogs need to be taken off to change the chain?
