Whilst at the recent MG & Triumph Spares Show i got speaking to an overdrive refurbisher who was making the point that the most common place for oil leaks is where the wire enters the overdrive box. Although he says there’s not a lot that can be done to prevent it i thought that to clean the area with meths and put some silicon over the area may help…….time will tell!!
