Humming Noise coming from motor Options

[kloudkicka]

Hey guys, not too sure if this is where i should be posting but, this is the first winter i'll be driving my car since i swapped the 3rd gen 3sgte and out of nowhere i hear a loud humming noise that gets loud and quiet and so on and i have no idea what it is, i try to take a listen as to where its coming from but i really can't tell, can anyone help? or has this happened to anyone else? kinda sounds like somethings struggling to move or turn

is it rev dependent?

maybe its something vibrating at its harmonic frequency? whenever I rev my car to 4000 and let of the gas, a whole bunch of stuff rattles in my interior as the tak falls. Thats just because the engine is vibrating in the perfect way for those bits to react.


a video would be the best way for us to be able to help you

ya it has nothing to do with the rev, even when the motor isnt running and i just turn the key to turn the battery on i hear it, i tried recording it with my phone but my blackberry wouldnt catch the noise of it, kinda like you gotta be sitting in the car to hear it which sucks
