5.0 Engine buzzing sound

[Skye]

I also have such a sound. Do I need to change the pcv valve?

The buzzing sound is a normal characteristic of the Coyote PCV valve. Brand new 2024 and now 2025 engines make the same noise. I wouldn't be concerned or change the valve on that sound alone.

If the valve sticks open, a greater amount of air enters the engine, often leading to poor idling. A secondary result is the sudden increase in oil consumption, oil being drawing into the intake system.

When the valve sticks closed, crankcase pressures can be high, resulting in oil leaks.

Unless you're experiencing lights, codes or other tells of a problem, I'd leave the PCV as-is.
