    Odd noise in engine bay?

    I came home after driving yesterday and noticed an inconsistent chatter or wirring noise coming from the front of the grill, I took a video to try and capture what I am talking about. You can hear it the most clearly from about 0:24 in the video. Im not talking about the DI pump clicking noise which is consistent, this is more erratic in frequency. Anybody have any ideas or normal operation?

    Are you sure it's not radiator cooling fan spinning. Sounds like air moving through radiator.

    Listen to a screwdriver/pokin' stick/stethoscope at the tensioner, water pump, and then general locations on the block to help pinpoint the source.
    Take everything I post with an MDOT truckload of salt.

    Sounds like a tapping noise?

    Valves?

    Both fans were not moving when I recorded the video.

    Valve chatter would be a consistent rhythm though wouldn't it? This noise is random, like an inconsistent loud vibration. I am finding a couple threads on ST engines making this noise, conclusion being drawn that its normal, but I know our motors are not the same.

    Agreed

    Try to pinpoint where the noise is most loudest.
    Will need some patience and time.

    Good luck.

    From the comments on the YouTube video, the person who uploaded the video said he's never had a problem with his car. He stated that he's currently at 44K as of 6 months ago. I would say the noise is normal.

    If I had to guess what the noise actually is. I'd guess it's probably the timing chain making noise. Just my 2 cents though.

    Yeah I saw the comments, plus the focusst.org thread that he posted his videos on has basically 6 pages of people chiming in and saying they all have it to, but again - our engines are not technically the same platform right?, im not sure how many parts between the 2.0 and 2.3 are shared.
