For the record we have two Discoveries, 1996 and 1999 and neither exhibit any "Gear Whine'. The only whine I ever hear is my wife wanting me to stop for something to eat...

The only time I had any whine in the engine room, it was a bad bearing on the alternator. You can take a long shank screwdriver, press the plastic handle next to your ear and touch the different rotating parts; AC, Alternator, steering pump, etc and hear pretty reliably which one is making the noise. For the bits that you can't safely reach, while keeping all your body parts safely clear, get a 3 or 4 foot piece of small diameter rubber hose. Fuel line is great and just hold one end at ear other endnear the component you are checking. You can isolate sounds pretty quick. We used the rubber hose method, to synochronize the three side draft carbs. on our MGB.

Good luck...

Is this while driving or standing still?
Diffs can whine, or the transfer case.

Ok so that excludes diffs and TC, do as Voyageur says.
Those idler pulleys and tensioner pulley can also whine when they go bad.
Keep your fingers and other body parts out of the fan and serpentine belt - unless you're not attached to them.

I just tried the screw driver on the alternator. Doesn't sound any different than my dad's truck's alternator. So I'm gonna rule that out. any other suggestions?

Anything that turns in that engine bay can whine, there's plenty there.
Could it just be the cooling fan that's kicking in? Check the electric fan as well, the one behind the front frill.

Tried everything I could reach. the rubber hose trick didn't work for me. there is a pretty bad clunking noise in the rear passenger side of the motor. it isn't rod knock. sounds more like chunks of metal in between gears.

Default Other Rotating Equipment

Do the same on everything else that is spinning when the engine is idling. Get a piece of hose, it's better for access. Serpentine belt pulleys, (Idler is one) AC compressor, Power steering pump, Water pump is too close DON'T check that. Do you have secondary air?

See if the sound comes and goes when you turn the AC compressor on or off.

Make sure power steering pump reservoir is full of fluid. Low fluid sometimes equals "Whiney" noise.

Also make sure there is nothing touching the cooling fan shroud or aux. cooling fan blades. Every once in a while an object from the road hits something in the engine compartment and busts a hunk out of some plastic part. A piece of broken plastic, rubbing on a spinning part, works like a phonograph record.

Good luck...

Jesse... I sent my last reply before I read your last post.

>>>sounds more like chunks of metal in between gears. Have a qualified mechanic look at it right away. I wouldn't drive it any farther than I had to. That is potentially a very bad sound.

Seriously? If it sounds that bad then I would not run the engine and have it looked at by a mechanic.

it isn't really That bad, but it is noticible if you have your head down in the engine. and it made it from north georgia to central florida just fine so I don't think its too serious.

Default Whine

If it's really high pitched it could definitely be an idler pulley. Mine had a really high pitched whine...until it froze, unscrewed itself, and allowed the serpentine belt to get caught in the fan. Not a pretty picture.

If it's coming from the engine compartment, try to find the source. Remove the serpentine belt and spin all of the components. These rovers do whistle and whine even when everything is OK, but anything out of the ordinary will not fix itself and could cause trouble down the road.
