Quacking Noise ?????

[DaveInSA]

Whats crazy is they did come listen… and the one salesman who has a bronco said his doesnt make that noise but then kept saying it was normal

Sales people typically know as much about the car they're selling (or own) as I know about brain surgery.

Aka, I know it involves a brain. That's it.

I would them check the knuter valve, though rare it can sometimes sound kind of like a duck quacking when it is not functioning properly.

Have them change the blinker fluid too. May be some duck sauce got in it.

I am having this weird “quacking” noise coming from whatever part this is in the pic below… (forgive me, I know next to nothing about this stuff).
Any idea at all what this could be? I have the 2.7.

Side note: I am also having a “whining” noise that you can hear while idling, and driving at low speeds. When you come to a stop, you can hear the sound “zip” off and go away….. anyone know what THAT could be?

Hey there! I can look into your Bronco’s noise concerns on my end if you’d like. Will you send us a private message with your VIN and dealership info?

Sound like Ford screwed up and accidentally installed their experimental one duck power 2.7L engine they were designing for the Everglades model.

All kidding aside, the hose in question is a vacuum line that's part of the engine emission package, it's part of the PCV system (positive crankcase ventilation)
