    Northstar diesel sounds

    I've posted this before but found any real answers. I'm also searched old posts and haven't found anything my North Star at low rpm's sounds somewhat like a diesel engine I've went to several dealerships and listened to several Northstar engines. A lot of them sounded just like mine and a few excellent. Here's a video from the bottom of the car where you can hear the sound better.

    I see no video.
    I noticed that mine sounds more "diesel" like when the engine beauty cover is off.

    Mine clatters like a '49 Oldsmobile with a flat cam. Those that claim to know say it's because of the VVT system.

    It's the VVT been answered numerous times. If you run regular fuel it makes it 1000x worse.

    Hahah worst Christmas present ever. Cute kid. My 07 STS sounded like that and I always just thought it was normal.

    So why is it that the sts I checked out earlier today sounded smoother than mine and a srx with the northstar has the same sound but not as loud as mine. ?

    Maybe because your running a shitty filter without an anti drain back valve which is why I asked....

    Start answering our questions and maybe we can help. You've provided nothing thus far other than your not satisfied with a noise your car is making.

    Hello B1n2fra,

    I apologize that you are dissatisfied with the noise that your STS is making. I do see that you mentioned you have went to multiple dealerships to test your vehicle against similar vehicles, but did you have the service department look into the noise to see if it was normal? If you would like any assistance working with a dealership, I would be more than happy to assist you. Please feel free to private message me if you would like to further discuss your concerns.
