ok my wife has an 06 ford Expedition
it was making a loud growling noise on cold start-up only (first thing in the morning) every day.... couldnt really pin-point it, i decided to take a video of the noise and post it over on the ford forums to see if anybody had a similar problem and the noise had changed to a loud, quick, aggressive rattle... here's the links to the vids
normal start-up, this video was actually taken after the second video

now here's the noisy one, once i open the hood there is a lot of wind noise but you can hear the engine fowards the end when i block the mic from the wind
