Hi Dave,
reg your first problem:
It's on the keyboard, just below the "L" and the ";", and below the "K" and the "L", makes life much easier.
reg your Landie problem:
I've heard it's a common problem, though I didn't encounter it myself. But if your OD isn't running dry and GB not running full, I wouldn't touch it, too small inconvenience to even start. Furthermore topping up OD is easier than GB, I do it from the inside

Cheers
Phil

thanks phil , amazes me how it does it must be a seal gone somewhere
