In the 1997 Nissan HB pickup it is located just behind the oil filter. Access the oil filter through the passenger side front tire firewall. Its easier if you are able to jack up the car and take off the passenger front tire. You have to remove the oil filter to get to the PCV valve. After you take off the oil filter you will see the hose just behind it. The PCV valve threads in to the right.
I just changed this over the weekend - what a mess!
