Default Clutch leak?

For the past few years I've had to add clutch fluid every few months. The clutch gets soft and the shifter gets notchy and I know it's time to add clutch fluid. It's also wet under the car, not crazy, just a small leak and it could be oil. Is this a sign of the clutch slave cylinder going? Could it be the source of my leak also? If I need a new clutch slave cylinder, how do I ensure I don't get one of the ones with the reversed seal?

I had the same thing happen with my 93 until the clutch started slipping. The slave cylinder leaked into the bell housing contaminating my clutch disc. I replaced the slave but am now nursing the car until I replace the clutch.

I ended up replacing the slave and the clutch pack.

You need to replace the clutch master, hose and slave ASAP, or you run the risk of damaging your transmisson. If you have a six speed, you should go to http://www.zfdoc.com and read up on the clutch hydraulic system.

Good luck, and let us know what happens

I sent my NEW, DOM slave to zfdoc and sure enough the seal was backwards. GREAT service from Bill.

Also you might want to check the carpet under the clutch pedal for a leak from the master cylinder.

Thanks for the info guys! Sounds like I need to do something yesterday. It is a 1994 6-speed. I checked out zfdoc.com and it sounds like the only gaurantee of a good part is to buy a cast slave cylinder. Has anyone had good/bad experiences with these? Alternatively, what does Bill at zfdoc charge to correct the seal on the DOM version?

No leak on the carpet. Do I still need to replace the master and hose at the same time?

Mine has been like this for 2 years. I'll replace the master and slave when I replace the clutch, when it finally goes.

Geez, quit putting this off or you'll ruin your tranny like I did. I had to replace 1st and 3rd gear and synchros, along with a bunch of other $$$ stuff.

I'm finally going to replace the clutch master and slave this weekend. I have the FSM. Any other tips?

I am looking at the Tru Torque master and slave. Are these parts reliable? Do I avoid getting a reversed seal by using this brand?
