Just to add to this since most part stores don't know if they're giving you the right one or not.
The valve shown in the other pictures in this thread seem to be
this one, the PCV1112 made by AZ Filters/luber finer from Autozone even though it doesn't match the picture on the Autozone website for this item.
Here's a picture of it compared to the one in my 2003 AWD Vibe:
As you can see, it's not a match but does look the same as other other ones in this thread. In my case with the 2003 AWD Vibe, since it's slightly smaller, it actually fit just fine and had just a tiny jiggle to it before fully tightened. Regardless I knew something wasn't right. Looks like my AWD Vibe has the 3/8 thread instead of the 16mm threads.
So I went on a hunt and found
this one, the PV1066 made by Purolator at Advance Auto Parts. It's the only one they actually carry at the store and I just installed it. Turns out it is the correct one. Here's a picture compared to my old one:
Also, the socket size is 19MM or 3/4 on my old and new one. On the other one that was incorrect, it was a 22mm socket size. You will need a deep socket and the Vibe manual says it's 22 ft lbs on the torque wrench.
Goodluck!
