clutch problems, help

i have a ADM sprinter with 20v silvertop, adm T50, and a clutch which is really starting to give me the sh#ts.
heres the story so far.
about a month ago at QR, my clutch went really firm and stated slipping i assumed it was the clutch line being to close to the extractors and boiling the fluid, so i wrapped the line in heat wrap and replaced the fluid. problem solved, not quite.
next hard drive, after a few clutch kicks it did it again. firm clutch pedal, clutch slipping, so i drove sraight home and the pedal slowly got softer. this time decided it had something to do with the throw out bearing as it had been squelling for a while.
so i pulled the box out and to my suprise there was a nice spray of oil inside the bell housing. Rear main seal had gone. so replaced rear main seal, clutch disk (not pressure plate as it was only 6 months old) and throw out bearing. sweet, problem solved,
Then a few days later, back to the testing ground (late night industrial estate). after 4 or 5 clutch kicks did it again. only this time wen i pulled over i couldnt get it back into any gear, turned off the car for ten minutes, then it was ok, pedal was still firm for most of the drive home. so decided it must be hydrolics so i replaced master and slave clutch cylinders.
did this on sunday, went for drive last night took the first few corners with hand brake then tried a right hander with clutch kick, straight away started free reving all the way down the road, so pulled over banged it out of 2nd and sure enough firm pedal and couldnt get it into gear.
sat for 10 minutes checking it every 2 minutes trying to get it into gear, then after the 3rd try pedal was nomal again went straight into gear and drove off normally.
WHAT IS THE PROBLEM?
sorry bout the huge post but i want everyone to get all the info so someone can help me. im now thinking its the pressure plate, but at this point ive decided to stop guessing. can someone with some knowlege tell me wats wrong with it.
thanks, jason

Not particularly sure.. but I doubt consecutive and repetitive clutch kicking would help the problem much...

when driving normally there is no problem, and i know that clutch kicking doesnt help but it is my drift car so its gunna hapen, and also im pretty sure there isnt oil in there again, even if there was why would the pedal get stiff when its playing up?

Did you bleed the slave when you replaced both cylinders??
You might have air in the line...

Probably your pressure plate man, with too much clutch kicking you may have damaged the release mechanism and it might not hold to the clutch properly...

Lol mostly any pressure plate wont ever lose its clutch release ability... You must have given it one hell of a workout...

Change your clutch plate as well. Doesn't matter if it's 5 minutes old - you get oil on it you've screwed it. Make sure you put some grease on the shaft the thrust bearing slides back and forth on as well. If that's dry it can put a lot of drag on your clutch movement.

this type MC design allows more fluid to enter when it is released quickly when the return flow from the slave is slow.
this extra fluid then closes the valve to the reservoir and you have a partially disengaged clutch & that pumped up, firm pedal feeling.
open the bleeder to release the extra pressure.
restricted hydraulic line or hose.
