Only happens when engine bought home after a drive and the oil is nice and thin, I get little drops of oil coming from this split pin at the very bottom of the gearbox.
I can actually push the split pin in (obviously up until the point where it splits!)
But why is it there? There is obviously a small hole there???
From the front

Close up

I dont want to bung it up unless its there for a purpose? Can't see what purpose it would have at the bottom unless it to let something escape, but oil?

Help please, my garage floor is like my bedroom floor........pure and holy
