General What do you think caused this huge hole in my gearbox?

[Firthy]

I've managed to temporarily patch it up until I get hold of a replacement box, and the car drives perfectly fine. The gearbox started making a whining noise in 2nd and 3rd gear one day last week, and when I checked I saw the hole. The box wouldn't hold ANY oil at as the hole is at the very bottom of the casing, hence the noise.

Anyway, I'd be interested in your opinions. Thanks in advance.

Simple
either a stone smashed while driving
Or something inside decided it didnt want to be part of the gearbox and left

dont drive the car
if it seizes you may end up killing someone

Could be road debris. Have seen a cat's eye jump up and cut fuel line and destroy the rear wheel. IMHO it would take a hell of a stone. What are the chances that someone was a bit careless with a trolley jack? Any work done recently?

I can't tell from the pic,
but if one edge is a lot Grubbier than the others - that was probably a crack for a while before the rest of it fell away,

trolley jack is a possibility,

as said it will probably seize on you if there have been grumbles in certain gears.

looks like something in the gearbox has decided to take a break
