a soft shake doesn't make any rattling at all..
a slightly harder continous shake will make a tiny rattle but it's not even...it will sorta make 2 clicks, stop then click again...if you know what i mean...
the proper way to test your PCV , is to CLAMP the rubber hose from the PCV while the engine idles.
If its fine working order it will CLICK CLICK or rattle as the engine idles. If no noise its likely clogged or failed so time to replace with a new one
