I've had this a couple of times, condensation.
I just changed the oil, ran it for 500 miles and changed it again.
No problems so far.

May be worth running a spanner over the various nuts and bolts holding the thing together - my TD one seems to have stopped leaking since I did this.

No excessive force - the bolts or studs will snap.

could this be the cause of a "whiring" sound when gear box in not under load. by that i mean i have just noticed a sound when car is in gear but not under exceleration

I'd have said no to the noise. The milky looking oil is a water/oil emulsion which will still have some lubricating qualities and indeed if it gets really hot may go back to oil.

The noise is probably the clutch release bearing - does it change if the clutch pedal is pressed?

My TD has made noises from the gearbox/clutch ever since I've had it (8+ years now). All goes quiet when the clutch pedal is pressed which suggests to me its the release bearing etc aned I'll wait till something else goes before attending to it.

Incidentally near the top of the box there is a plastic vent - Is it still there? Is water running in its area which is getting into the box?

Whirring does sound like it could be the clutch release bearing. I've had cars that have had this problem and had thousands of miles out of them. Worth doing if it gets unbearable or, of course, if you have reason to split the engine/box anyhow.
