Hi Manfred, there is a small spring and a clip that should be fitted to your gearshift lever - the spring goes under the dished oiling cover, and the clip goes over the oiler cover - this will prevent the rattle from the oiler cover. best regards.
I had one years ago and believe me you never forget your beloved MG. Although I could not even get in to my TC now if I still had it, I wish I could just look at it with love and keep it clean and just know that it is there. Owning an MG is so much more than just having a car. It is a bond, a relationship like no other.
