What is this? (172 G'box)

Is this the drain hole minus the plug for the gearbox oil??

Would explain the mess!

Thanks.

it doesn't look like it. The drain is further back

I think it's an unused casting point. The gearbox drain is a far larger diameter I'm sure?

Brilliant, thanks!

The mess must be engine oil then, due to the tiny hole in the sump!
