Loud Roaring and Whining Noise
I have a 2004 Disco and when I do a cold start-up, there is a very loud roaring noise from the engine compartment for about 2-3 minutes then it stops. I never hear it again until the next cold start-up.
Also, when I turn on the AC, there is a loud whining noise only during acceleration. When I turn the AC off, I do not hear any whining at all.
Ideas/suggestions?

The loud roaring on start up is the lion waking up from its sleep, that's normal. Actually its the secondary air injection pump you hear, this only runs on cold start up for a few minutes. If it's really loud then the pump could be faulty.
The whining noise could be your serp belt slipping, check your serp belt for wear and tension.

Check for cracks, its 6 years old and most probably needs to be replaced by now.
