Just a quick question . If my gear box was leaking oil would it leak all the time or just when you move (changing gear while drive) . I no it sounds a bit drange but it just I've changed the side cover on the gear box because it had a hole in it and was leakin , and I just drove to my mother inlaws house and I looked underneath and the is a line of oil on the floor right under the gear box, so I looked around but could not see any drips, so I put some card down to see if leaks. Thanx ian
