How to Change the PCV Valve on a 2004 Ford F150 5.4L

The Ford F-150 was introduced in 1975, and it eventually replaced the F-100. The 2004 Ford F-150 was available in 47 different trim packages. The 2004 F-150's 5.4-liter, 300-horsepower V-8 was an optional engine upgrade from the base model's 4.6-liter V-8. PCV in automotive terms stands for "positive crankcase ventilation." The PCV valve opens and closes to regulate the pressure and remove extra pressure from the engine's oil system. Replacing the PCV can be accomplished in a matter of minutes, depending on your mechanical aptitude.

Remove the PCV valve from the right-side valve cover, by hand. Separate the PCV valve from the PCV valve tubing, by hand.
