2024 Mustang GT

[Vapor Blue GT]

I had my car looked at for this exact noise a month back. The master Tech explained to me it was the Check Valve on the PCV. Essentially there is a small metal ball on a spring to open/close the PCV valve. As the car runs it open and close in no orderly fashion, just as it needs. So this is no real threat or thing to worry about, is kind of annoying though.

Glad you found the culprit. The other thing interesting is that I’ve never seen a ball in a pcv valve. Just a spring and a piece of metal or plastic. I’m now curious as to what our pcv valve looks like.

Mine has developed this tick after its first oil change. It might be my mind but it seems to have increased in volume.

This almost sounds like an ignition spark going to ground. It's random.

The morse code noise or the rotating assembly sound?

The Morse code one should be heard more under the vehicle by the oil pan drain plug area

Yes the Morse code tick is more noticeable underneath. That is the one that started just after the first oil change.
