You're welcome, happy to help (or try to help). Symptoms still point towards a slave cylinder problem to me though, or a dodgy clutch but you said that was brand new. If you have a spare slave cylinder it may be worth trying that. I've had the same trouble before when forgetting to bleed the clutch after fitting a gearbox/clutch. The release bearings are the same, the input shaft size is the same on the gearbox. I can confirm this tomorrow but I am 99.9999% sure the release bearing shouldn't be a problem, unless it's fitted wrong.
