Where is the pcv valve located? I have a 3.4.

 

Should be right of where you fill your oil, theres a lil rubber thing that goes down just oull it up pull out the old PCV valve, pop the new one in

 

I'm not sure about the 3.4, but on the 3.8 you have to be careful because there is a spring in there too.

Again, not sure about the 3.4, but be careful. I dropped the spring and spent like 15 minutes looking for it.
