Default hydrolic/brake fluid leak from clutch housing (late 944 n/a)

I recently bled my brakes/clutch through the use of a power bleeder after resealing some of my brake cylinders. And now the system seems to be leaking as the clutch is loosing pressure.

I just pulled the starter and began to bleed the slave again and as I did i realized the leak is coming out of the 1" inspection hole on the clutch housing

Any Ideas on what could be leaking? I already have the feeling I will be doing some serious disassembly to follow but I would relly like to know what I am trying to fix before I tear the whole thing apart.

Clutch slave cylinder... leaking from the shaft inside the bellhousing.. get a new one, takes 10 minutes to swap, might also want a new master and the hose in between at the same time... master will add some time, but is a good idea to change at the same time.. hose gets brittle, and can split when moved durring the slave cyl changeout...

Even with a lift, I think 10 minutes is grossly underestimating this task.

To get the slave cylinder out you'll need to remove the starter heat shield, drop the starter, and then remove the slave cylinder. More importantly, bleeding the slave cylinder will definitely take some time to do properly.

I think it's good to give people advice but there's no need to make things sound easier/faster than they really are.

Thank you, I was kind of thinking I might end up pulling the clutch, but if its the slave and all I have to do is remove the starter that's a relief as I have already done that a couple times and its no big deal.

Luis...you are absolutely correct. While this is an easy job, its not 10 minutes.

If you don't have a turbo, you might not even have a heat shield, which saves some time. Either way, you are in for jacking and properly securing your car so you can get under it, removing a hydraulic line which may or may not be rusty and stuck (and break as you are trying to remove it) and 2 other bold to even get the old stuff off. There's at least 30 minutes in an average NON AUTO SHOP garage.

Then you toss the new one in and hook it up. If the first part went well, this takes even less time. So now you're optimistically 45 minutes into this job.

Now you hopefully have a pressure bleeder. You fill it with fluid and bleed your clutch. Another 15 minutes if all goes reasonable well.

Now everything is probably working, if all went well, and at least 1/2 of your car is in the air. Get it back down and you're at over an hour give or take.

Not a big deal, but NOT 15 minutes.
