Where is the PCV valve located on a 5.4 liter Ford engine?

The location of the PCV valve on a 5.4L Ford engine varies slightly depending on the year and specific engine configuration (e.g., Triton, Modular). However, it's generally found on the top of the engine, near the back, usually on the passenger side valve cover.

It's often a small, round, usually black or dark-colored valve. To be certain, you should:

* Consult your vehicle's repair manual: This is the most accurate way to locate it for your specific year and model.

* Use an online parts diagram: Many websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, and model and view a diagram showing the parts, including the PCV valve.

Don't rely solely on a general answer – always double-check using your vehicle's specific documentation.
