Truck making wierd... sounds?
For the last couple weeks my Tahoe has been making this very odd fluttering whistle like noise. You can hear is on start up and it soon fades. But... As I start driving and acceleration under load its back. A Fluttering, whistle-esque like continuous noise. I have a video although it doesn't do this noise justice. I'll upload it as soon as I figure out It sounds like its coming from back of the motor. Under the truck whilst it is being rev'ed sound frightening to say the least.

I made sure everything was tight. Header bolts, band clamps, o2's. Nothing else past that. Also checked under the valve cover. everything seems to be running smooth. The sound is coming from below the headers. bottom- rear of the engine.

Some have heard a knocking while others say there is a buzzing.
It's all crap to me until I start poking around and listening to different area's.
Bad cam bearings can sequel as well as when the lifer roller seizes up.
Now that I listen again it sounds like the power steering pump is whining.
