weird high-pitched noise?

Hi All,

My E30 325i has recently developed a new noise in the engine bay: a high-pitched almost whistle kind of noise when I press the accelerator. (It might be coming from under the rocker cover...)

I've got a short video clip, but I don't know how to attach it to this forum message. Can anyone let me know how I can attach it? Thanks.

Thanks for the reply. I've just figured out how to put it on Youtube.

Here's the video clip...



Hopefully somebody will know what this noise is...

Thanks.

That almost sounds like exhaust manifold blowing, check around the joints to the cylinder head, use a piece of hose as a listening device.

Thanks, I will definitely try that, and then post an update here.
