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

O.K. i think i have the answer
i was talking to a clutch specialist this morning who came to the conclusion that my clutch line that runs past my extractors was old and absorbing alot of heat, his theory was that the flexible line, (being made up of multiple layers of material) had developed a split on the inside wich after high revs and high heat flares open, creating a pocket in between the layers of material wich catches the fluid and therefore does not operate the slave properly.
does this seem possible?
it seemed to make sense to me.
Im replacing the line tomorrow so i will post my results
i thought this was important to post as most 86's have there line and slave running close to extractors.

how many of these have you posted??
have you read any of the others????????????????????
i really doubt that it is heat related, and "high revs" concerning a hydraulic line is just pure BS.
what is a "clutch specialist". i am sure i am not one.

um, im not really sure wat your talking about, wat others?
and wat i was talking about was that because my slave and flexible clutch line sit right next to the engine bays primary heat source the extractors the old and brittle line when heated up from high revolutions of the motor and therefore increased heat being eminated from said extracors, would distort and damage the line causing a restriction in clutch fluid, roger?
also changing the line has completly solved my problem and has so far taken a fair amount of punishment with no hassles
next, a clutch specialist is a workshop that deals only with clutches and brakes (hydraulic systems)
and finally no you are not a clutch specialist.
so maybe you should put your sword away keyboard worrior.
