Where is the PCV valve on a 1989 Ford F 250 with 5.8 L 351 windsor?

The PCV valve on a 1989 Ford F-250 with a 5.8L 351 Windsor engine is typically located on the passenger side valve cover. It's a small, usually black, cylindrical valve with a hose attached to it. One end of the hose goes to the valve cover and the other to a fitting on the intake manifold.

However, it's crucial to double-check your specific engine. While this is the most common location, slight variations can occur due to different production runs or modifications. The best way to be absolutely certain is:

1. Consult a repair manual: A Haynes or Chilton manual specific to your year and engine will have a diagram showing the exact location of the PCV valve.

2. Use an online parts diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) allow you to look up parts diagrams for your vehicle. Entering your vehicle's information will show the PCV valve's location.

3. Visually inspect the passenger-side valve cover and intake manifold: Look for a small valve with a hose connected to it, as described above. Trace the hose to see where it connects.

Remember to be careful when working on your engine. If you're unsure about anything, it's best to consult a qualified mechanic.
