Changed clutch slave cyl
First went to Auto Zone, couldn't get them any more. Went to O'Riellies next, they were now $79 instead of $50 for the cast iron version.
My car has TPIS long-tube headers so there's room to change these out. I just used the old studs, it's a bit tight with that round part sticking out of the transmission but it goes without too much struggling.
I let the front end down off the stands and raised the rear end to assist bleeding. Took about an hour or so before there was a full peddle. Clutch feels much better now

I did this job not too long ago on mine. Bleeding sure was a pain but the best part is nothing is leaking anymore!

I have read on here, those studs make it almost impossible to get the new cast iron version on. Now there is a little snag I forgot to mention. I used a 1/4" drive deep 1/2" socket (thin wall) and it was still difficult to get the socket in there. Need to take a Dotco and cut-off disc to make room on each ear. That way the socket fits onto the nut without rubbing the slave cylinder. Pics would help show that.

Just changed my slave cylinder on a 96 six speed. Had exhaust off. Don't know if it could be done with exhaust on. Replaced original slave cylinder with cast iron version. Mounting stud length was not an issue. Used a 3/8ths drive, 1/2" socket on an universal joint with two long extensions to remove and install nuts on mounting studs; no problems there.
Bleeding the slave cylinder is another story.

^^I've been told....
the tech tip is to fill the Slave and the inlet of the hose and keep it level and full as you put it in place. Then attach the hose.
then the thing is supposed to self bleed....the trick being that the Slave has no air in it......I've been told

I will say that the ZF hydraulics is the easiest system to bleed that I have ever owned....
the 4+3 slave has a small chamber at fluid inlet end and it has a tendency to hold air in it...

The easiest and fastest way, IMHO, is to remove the bleeder screw and carefully (6-7 turns) wrap threads with teflon tape and re-install. Empty Master if not already. Using My-T-Vac or similiar, fill thru bleeder screw upwards to the Master so the air naturally escapes. I finally got a firm pedal and it didn't take much time.

Use a Phoenix Injector, as recommended by Bill at ZFDoc:

Once you use one of these you'll wonder how you lived without it when doing this job. And by the way, these guys have great customer service.

I just let it hang down with the bleeder end up, and I press the plunger in several times at various angles...then bolt it on.
Also, I bought a Speed Bleeder to put in the slave bleeder hole.
