FYI: During the clutch bleeding procedure if your clutch system stays soft and spongy and you always find air in the slave cylinder after several attempts at bleeding then you may need to check the bleeder valve seats for pitting/dirt and the threads in the slave cylinder for stripping. While bleeding my system I discovered that the bleeder valve threads in the slave cylinder were giving way & stripping which failed to provide enough pressure to make a tight seal at the valve. New slave cylinder on order from RodneyDickman.com .

If the valve won't tighten down I can see you would have a problem, but it does not seal on the threads, it seals by closing off a hole in the bottom, so loose threads have nothing to do with leaks. Larry

Correct, valve threads were stripping away and eventually would not tighten anymore.

I had that same problem about 6 years ago. The ball end of the bleeder had pitted. I polished it up and the pedals been hard ever since.
