Default Clogged PCV and vvt solenoid

Hi!
Have a clogged pcv(air blowing out of oil filler cap)
At the same time vvt solenoid is making its trademark noise. Put a new one in and still the noise persists.
Is the pcv causing oil starvation at the vvt valve?

It's normally the VVT pulley/sprocket that makes the noise.
PCV doesn't normally cause this problem, but an oil & oil filter change can sometimes improve things, depending on how worn the VVT pulley/sprocket is ?

I see..I was certain it was the solenoid.
Engine sounds sweet with disconnected though.
Very strange.
Will change the pcv first and then the sprocket.

Not strange at all really . . . when the solenoid is disconnected the oil supply to the sprocket is removed , causing the sprocket to become locked in it's neutral position. Then the noise disappears.
You loose a bit of horse power, that's all.

And it won't damage the engine if I drive it disconnected for a few days until the parts arrive?
