unplugging vanos solenoids while engine running? Bad?

So I want to narrow down if the marble sound I have coming thru my dash is the vanos solenoids. (noise is rpm dependent)

IF I unplug the intake and the exhaust solenoid while the engine is running during idle, is it harmful for the engine?

this way I can see if the noise stops? I know for sure its the vanos solenoids.
