PCV valve

I have a 2004 ford taurus and the pcv valve needs to be replaced. Can someone walk me through where that is? I am not a car person so I am a little lost. I have the part. Auto zone said it was easy. help

Here’s where it’s located on the 2 valve engine.

And here’s where it’s located on the 4 valve engine.

thank you

Make sure you put it in with the correct orientation. It is a directional valve. Compare to the old one, before removing the old one from its hose.

Also, curious why you think you need a new one? Any symptoms?
