    Guys, ano kaya yung mga causes ng whistling sound after mapahinga yung makina, naririnig ko to usually sa mga first 5 mins na pinaandar ko yung makina.

    does it mean that it is time for replacement?

    Whistle type sounds are usually made by intake leaks. Check in the intake manifold area under the hood when the temps outside are right for making the noise. It could be anything from loose bolts to a broken gasket or a faulty hose or sealing cap. Spraying some carb cleaner solvent on the suspected areas to help pinpoint the source of the sound. Remember to torque the bolts to manufacturer's specs when everything is cold under the hood.

    Hope this will help you.

    more questions than answers.

    your question is very similar to mine.

    imo, it doesn't ALWAYS mean bad. since I hear this on mint cars too... I even hear this on tv's and movies.

    Imo, if it aint belt, it's vacuum leaks. try starting the engine on cold while air filter is removed. see if mas loud ang whistle.
