Mini rod-change selector shaft seal
Selector shaft seal, suits rod change.
Mini leylands ran two rods to the back of the gearbox, one of these rods had a seal that prveted oil leaking from the gearbox, quite often however the oil and the heat from the nearby exhaust damages the seal and it becomes hard and brittle then will leave a little trail everytime you park the car....
Stop that leak (so your partner doesnt give you stick about the mess in the driveway :-) )
A little trick is two put two new seals in (there is enough room) this will really stop it leaking
