The PCV valve is a one way valve. If it's bad it will either get stuck open or closed.

I usually check/replace it when I get idling issues.

or smoke.
when they go bad in a 300zx, you get all kinds of fun tail pipe smoke.

But, I'm pretty sure they are intended to last 60K miles. But I have had cars with 120K miles and the stock pcv valve on them.
