I have a video clip with my car at start-up, a loud whining noise that comes from the engine compartment. Blackbird thinks it might be the waterpump but that was from just a description of the sound. Anyways, here is the link to the clip:

hmm... was that car warming up or was it warmed up? Sometimes i some loud engine noises when i start the car, then it just goes away and its silent like hell.

 

it was that drilling noise... stays on but gets a tad quieter.... but its rpm dependant.

 

The engine needs heat...that's what it is. Let it warm up before you move it.

 

well its really loud when its cold... but that drilling noise is always there... just happened maybe 10k ago... even when the car is running for 3 hours traight i can still hear it. it never used to be there, unless it is and you guys have that sound also....

Hmmmnnnn....mine does something similar, but it's more high pitched then yours. Yours is more of a mellow hum/whine, mine is squealy/squeaky sounding.

Can you get a clip from the engine bay with the hood up?

Try and narrow down where exactly the sound is coming from, ie front of engine(passenger side), front/rear of engine bay, and top/bottom of engine.

Mine is right in the middle I think, so I'm thinking tensioner pulley but I'm not sure.

 

I had A little Squekky Noise in the Engine compartment, when i first used to warm up my car but everseince i Changed my Under Drive Pulley, it went away. BUt It might be Because of the Belt. I knew mine was because of the belt thats why i went ahead and changed the Crank pulley.....

 

Sound like power steering pump....Did you check the P/S oil level yet ?

 

Take a long screw driver and place one end on your ear and touch each device with the other end. When you touch the device thats making the noise, you'll hear it transfered very clearly up through the screw driver into your ear.

My bet is on the Alty.
