Because it's tucked away in the engine bay, a picture is more helpful than a description. I recommend searching online image searches using terms like:
* "1995 Chevrolet Camaro PCV valve location"
* "1995 Camaro 3.4L PCV valve" (or "3.8L" depending on your engine size)
* "1995 Camaro LT1 PCV valve" (If it's the LT1 V8)
These searches will show you pictures of the valve in its typical location on the Camaro's valve cover, which is your best bet for identification. A visual comparison will be the most reliable way to identify it.
