I know this is probably a stupid question, I did search and all I could find was that people needed to bleed their clutch. I am pretty sure that is what I need to do and if my problem persists I will need to replace the clutch cylinder.

But the question is how do you bleed the clutch? I have tried to find a bleed screw but I really couldnt get under the car, but this weekend I will be at my parents house and be able to jack it up.

If it comes down to it, how do I replace the clutch cylinder?

Thanks.

The bleed screw is on the slave cylinder. See FSM page H-11.

Are you losing fluid?

The Mityvac is a fantastic tool to add to your toolbox.

Thanks for the reference. I have not lost any noticeable amount of fluid from the reservoir. But there is a residue on the slave cylinder, I tried to smell it but it has no smell. The car was sitting for a week and there was no residue, but after I had it towed to my parent’s house and it has been sitting for another week, I started noticing the residue. I want to bleed the system first before I buy new master and slave cylinders. Another question, if my clutch system was failing, would any problems with my brakes be evident?

That's why I asked about the fluid. The clutch shares a fluid reservoir with the brake system. If the clutch cylinder is leaking fluid, replace it and bleed the clutch. In the meantime, keep an eye on the fluid level if you drive it.

I replaced the slave cylinder yesterday, and I tried to bleed it for about 30 mins. Every time I have my brother push down the clutch, an air bubble forms in the reservoir. Like before, there is no fluid leaking and the break pedal feels fine. Do I just need to continue bleeding the slave cylinder?

If you have a air bobble than you have a air leak some were. If you have a performance clutch you may want to put in a ss clutch line.

I am going to put the SS line on tomorrow. I was also wondering, when I put the slave cylinder in, was I supposed to make sure that the piston was pushing against something? And something else I noticed, was that when I had my brother hold down the clutch, fluid would leak out of the bottom of the transmission. There is a small square cover with a bolt in each corner. Is this going to be a major problem and how do I fix that?

When you installed the slave you didn't get it located into the release arm. Now that you've put pressure on it you have more than likely pushed the piston out of the slave. My guess is also that you have no pedal (have to pull it back to return position) You will need to take that cover off and get the piston to the slave cylinder out (if it didn't stay in th slave) and reassemble everything and try again. That's why fluid is leaking out the bottom.

How do I get it located into the release arm?

You just have to be careful when your putting it in and try to keep it aligned. You can tell its on becuase it will give you a little resistance and want to push itself out a little bit.

The air bubble in the reservoir could mean a leaky seal on the clutch master cylinder.

You can always use a speed bleeder for brakes on your slave cylinder. edlebrock sells them. Makes the job a one man operation. They have a check valve in them so air can't go back in.

I have done some research on the speed bleeders and they sound like a hell of an idea, especialy since I am not really sure on how I am supposed to be bleeding the slave cylinder. It just seems that the speed bleeders take the idiot out of the job. The pressure was better when I first installed the new slave cylinder. I went to Auto Zone, Advanced Auto Parts, and Wal-Mart and the ones they have are short and fat. I am still going to order one, anyone have the size off hand, I do not want to guess and order the wrong one.

Here is my thread from when I was trying to install/bleed my clutch including link to google vid:

You are right, I have less pedal now then I did before I replaced the slave cylinder. I will take the slave cylinder off tomorrow and see if the piston is still in it. Today I put on the SS line, a lot easier than I had thought it would be. I started bleeding and that was going well. Then I noticed a lot of fluid coming out of the bottom from that cover. So let me see if I understand this correctly, for whatever reason I did not line up the slave cylinder correctly when I installed it and the slave cylinder piston came off. Now when I push on the clutch pedal the hydraulic fluid is leaving the reservoir going through the SS line into the slave cylinder and then just coming out the bottom where that cover is and the piston is probably just chilling on the bottom of the transmission housing.

You guys were right, I took off the slave cylinder and the bottom of the boot was ripped open and the piston was barely holding on. I was able to replace the boot from the old slave cylinder. Hopefully I can line it up better this time. Thanks guys for all of the help.

Well after getting the the slave cylinder back on and my speed bleeder installed I still have the problem I had before. Although the system hold much more pressure than before. I have a master cylinder in the mail and hopefully this is the problem. I did notice today that when the car is off I could change gears without pushing the clutch down. Does this sound like a broken or bent clutch fork?
