Ok so I searched as best as I could for the cause of this here and through asking a number of my mechanic freinds and I cant figure this out. I have a 1991 240 SX, which I was bleeding the clutch on earlier today and unfortunatly allowed air into the system through the cylinder. Untill then I had no problems and everything had been going fine, so i refilled the cylinder with more fluid and went to re-bleed it to get the newly introduced air out and now the clutch wont come all the way back up, and I cant fully dissengage the clutch any more. I have bleed out about 2 times the capacity of the entire system now and it still wont work and I know that the bleeder is closed compleatly and there is no leak does any one have any ideas what the heck is going on here?

ok so I tryed the gravity bleed and it did nothing no more air then before. At this point I have blead it from the valves at both the cylinder and the little box thing and by the way if any one knows what the box is that the line goe into before going to the cylinder I would appriciate the proper name so as to stop calling it "that weird box thing." the only real progress is that I pulled the valve from the box all together and un-clogged it because it wasn't flowing at all. I am still very confused could some one please give me something, any thing??

that little box is called the clutch damper box. its useless and makes bleeding your clutch 100% harder than it needs to be. if you take that box off and bend your hardline to where you can screw the rubber line into it, it would make bleeding your clutch easier/less time consuming. its not hard, but if you attempt this be very careful not to kink the hardline. i did mine, and it was hard to bend at first, but after a few mins of putting pressure on it it started to slowly bend. then youll need to refill your clutch master cyl and re bleed the system. shouldnt take but 10 mins to bleed if even that.question: why did you bleed the clutch in the first place? did you replace your clutch master/slave cyl? replace a busted line? or what?

the pedle had a squishie feel to it and it wouldnt fully disengage til it was on the floor I was hoping that bleeding it would fix this but I did not realize that I could only bleed it 4 times before needing to re fill it on the 6th it went to the floor and died
