Leaking Clutch Master Cyl. from cap??? WTF

Hey guys not big on making new threads but searching is coming up with nada.

Just like the title says I am having a problem with the cap. It seems like it will not seal. I can drive it on the road w/o leaking but I have to check the fluid often when on the trail because it leaks out. There is a rubber seal in the cap.

I have replaced the master cylinder twice now. I was thinking that the first one was a defective unit but the 2nd master cylinder is doing the same thing.

There is a notch cut out in the threads that would allow fluid out but shouldn't the rubber cap keep it from leaking. Can post a pic if it would help? The clutch works fine but I feel there is low pressure in the system. The clutch feels slow to engage from a stop and catches near the top.

I also replaced the clutch and in the instructions (yes I read instructions) it said something about a shim for the slave cylinder. I called the dealership and said this part is discontinued. Any idea where I can get one?

probably get a shim from like any mechanic place. A shim Is NECCAsary for having the clutch. Im suprised the clutch works correctly without one. The overflowing is prob either a bad cap(go to any local parts store and grab one) or your vent hose is clogged

Can you please explain more on the vent hose? This is the 2nd master cylinder from a different company and it has the same problem.

Any idea where I can get that shim??

I forgot to mention that this is on a 94 YJ with the external slave cylinder.
