Where is the PCV valve located on a 1993 Nissan hardbody truck?

It took me a while to find mine. It's been a while since I changed mine, and I tried to find the exact location again, but I could not see it. It is on the passenger side of the motor, close to where the water line to the heater comes off by the thermostat, and if I rememeber correctly, it's under the intake manifold. If I remember correctly, it's not directly on the motor, but off of a pipe, but I'm not sure. Sorry I couldn't help you more.
