Default Moving (but consistent) clutch engagement point

I've got a weird issue with my 2000 Outback (with ej257 swap, ver5 sti transmission swapped) that's been there ever since I bought the car.

The clutch engagement point (the point in the pedal throw where the clutch grabs) is set very high in the throw. Almost as soon as I start to depress the pedal the clutch disengages.

Whenever I have the clutch pedal depressed for more than a few seconds, the engagement point drops from its normal position to right on the floor prettymuch. As soon as my foot starts to move the clutch will grab, but not fully engage until the pedal reaches the point where it normally would if I just pressed the clutch in for a gear change.

I've asked a few people locally and they say that that sounds normal, but I've never seen that on any other car unless either the master or slave cylinders were on their way out.

I've also done some reading that there's a 'clutch delay valve' that does something similar, but this seems to be on the extreme side of it.

I'd like to get this dealt with so I can move the engagement point more to the middle of the pedal throw and have it there consistently. If I were to do that now, I don't think I'd be able to pull the car out of gear if I sit with the clutch in for more than a few seconds.

Thanks for any ideas!

Took a look and there's nothing resembling the clutch delay valve 'disc' on the master cylinder. Not really sure what else could cause this then?

I would say the master cylinder is shot, easy enough to change out at this point...

Think about it, whats moving tue fluid for the slave?

I would say one or the other is bad...
