I've driven probably 1000ks on this new gearbox, so don't think its a running in issue - thanks anyway...
I spoke to exedy, they recon it is the box, gearbox guy recons its the box, mechanic recons its the box... who knows...
I can't logically think it could be the thrust bearing - maybe if it was a push type clutch, but not a pull type - there is noething for it to rub against etc... and the load on the thrust is when you push the clutch pedal down... which is when my noise goes away... doesn't make sense... but we'll see...
