By way as a quick intro, im based in Peterborough and bought a Super Six back in May which has made the long hot summer even more enjoyable!
Whilst out recently (but luckily only a mile or so from home) a grinding/crunching noise started somewhere in the drivetrain. Ive taken the car out again and it sounds as though its coming form the gearbox. The noise occurs in 4th and 5th gears when coming on and off the power and also constantly whenever the clutch is put down over 30/40mph in any gear.
Ive got no experience of gearbox issues so can only assume this might be something like the input/output shaft bearing. Is anyone familiar with this and advise where the issue is likely to be coming from? Could the issue be diff related rather than gearbox?
The car has a silver top Zetec, type 9 gearbox and cable operated clutch. There has been a small leak coming from the gearbox when the car has been driven but not when stored - i think it is coming from the front (bellhousing) end but cant say for sure. Ive put the odd 1/4 litre of oil in the box so confident it has never been too low, but guess this could also be a sign of a failing bearing?
Any help is massively appreciated. Thanks, Aaron
