Is it normal to hear a rattling noise at the PCV vale while running?

I'm told the dealer PCV valve is best. This one has been on it for about 10 months. Basic one from parts store.
I know you shake it to test but wasn't sure when running what that may mean.

Hi,

The PCV basically limits air flow in one direction. So, when you start the engine, you may hear a click when it opens from the engine vacuum, but it shouldn't rattle when running.

Is that what you mean?

Let me know.
