It appears the diff on the gearbox of the 16v is the cause of my annoying noise. Basically it makes a sort of constant clicking noise and it appears to be the cause. Basically I just wondered if anyone knows how long it's likely to funtion OK for even with the noisy diff?
The thing is that it's just had a new box put on not so long ago and tbh I can't be arsed with the hassle of putting yet another new box on.
