bled clutch ,slave cylinder has been changed, have two original one from 4 speed and 5speed both same changed it due to doing more longer journeys and it needed the extra gear i didn't change clutch or pressure plate as i didn't think they would be an issue as both are 12v boxes yes re used old release bearing wasn't growling or whirring when foot on or off clutch no i removed both 12mm bolts as just moved it out of the way so no need for bleeding clutch no original was replacement is fine not leaking seems i have come to the conclusion is the flywheel and clutch flywheel is to narrow thickness wise so basically box is sitting into clutch fine but isn't close enough for the release bearing to fully disengage the clutch plate basically when i pressed the clutch the pressure plate wasn't pushing the clutch disc far enough away from flywheel causing the disc to drag on flywheel
