To find it:
1. Locate the valve cover: This is the topmost part of the engine, often with a noticeable rectangular or oblong shape. It's usually made of metal or plastic.
2. Look for a small, usually plastic, valve with a single hose connected: The PCV valve is relatively small and may have a slight indentation or a cap on top. The hose connected to it will typically be thin and routed to the intake manifold.
3. Check your owner's manual: If you have the owner's manual, it should have a diagram showing the location of the PCV valve.
4. Consult a repair manual: A Chilton's or Haynes repair manual specific to your 1995 Nissan pickup will give you precise diagrams and instructions. This is the most reliable method.
Caution: The engine will be hot after running, so allow it to cool completely before attempting to locate the valve.
