It will leak at the bell housing/torque tube connection if a leak is present. Keep an eye out that's all you can do.
If your driving around and it doesn't slip or grind gears and engages well, you very well may be over thinking about it. Even the slightest bit of air in the system makes it difficult to shift smoothly.

I had the slightest leak from my remote bleeder connection at the slave. It went from good to terrible overnight because of it. If you experience no issues such as slip or difficulty shifting I say leave it

I tried that easy bleeding method. It made it worse somehow. I'm making a DIY pressure bleed so I should be able to flush/bleed the whole system this weekend. I'll check back in then. Have a great week 
Now time to go find a spare cap since the cap can only be purchased along with the master cylinder

with work, online course, and now the vette issue. I completely forgot about this drain thing I saw earlier last week.
Thank you Joe and Brian for your help once again! I will check back in

I couldn't wait until the weekend... despite working 10 hours a day and got couple of projects due Sunday.
I was able to pressure bleed it today using stuff i had purchased from ACE Hardware and a cap i had found at Advanced Auto.
After pressure bleeding the clutch from MC, the clutch pedal was all the way to the top & LOTS of pressure.
1st pump was perfect
2nd pump was perfect
3rd pump the clutch pedal only went up 95% ish and i feel the spring brings it up.
after 4th pump it stayed the same. It goes up about 70% of the way. not far enough for the spring to kick in.
I bled the clutch again and did the same exact thing.
The clutch is actually a lot better than couple days ago. It goes up twice as much as the other day. No clutch slippage and no gear grinding. no leaks.
Starting to make me feel like it's the slave cylinder.... I just ordered a vacuum pump and it should be here next Friday. Lets see if that works. if not, i'm done...

Hello,
It's nice to meet everyone. I'm having issue with my 2005 vette c6 z51 and I was hopping to get some helpful inputs. My vette has around 50k miles and the clutch pedal is on the floor.
The car drove perfectly all day (I did burnt the clutch because of noob shifting from 1st to 2nd....). Pumped gas drove the car home and everything felt normal. Clutch pedal pressure and everything felt the same.
Story:
Few hours later. I was cleaning the inside of the car. I had decided to start the car and play with the shifter. It went into all gears perfectly. I placed it on neutral and start popping the clutch while parked. I wanted to see if there's any differences after I burnt the clutch earlier... As expected, the clutch pedal pop back to normal position real fast. I popped the clutch 3-4 times and the 5th time it got stuck! I pulled it back up with my foot and pressed it and nothing....
I opened the master cylinder cap and fluid is empty... i had checked everywhere for leakage and there's none. All hose and tubes appears to be perfect.
Attempts to fix:
1.) I filled the cylinder with dot 3/4. and started pumping the pedal. The fluid went down from full to 1/2 full. filled it to full again - pedal still down.
2.) I tried pumping the clutch and releasing the slave cylinder bleeder valve. I repeated these 2 steps about 10 times. The fluid level remain the same. Pedal still to the ground.
Future Plans:
1.) I'm building a pressure bleed from a DIY I found on google. and try bleed the system again.
2.) replacing the clutch on my own - if i don't want headaches, i'll just go with step 3 LOL
3.) Take it to the mechanic and have the clutch replaced and hopefully they can just fix this issue for me.
Any inputs would be great! thank you!

ehhh! i hope it's not the slave.
UPDATE:
1.)i drove her around on the weekend and the clutch pedal seems to be getting better as i drive it!
2.) i finally got a vacuum bleeder and i tried bleeding it through the master cylinder during lunch. I saw a lot tiny bubbles flowing to the top after pumping it to around 20" vacuum. I kept it at around 20" for 5 minutes. got back into the car and pedal was to the ground. I pumped the pedal around 40-50 times and the pedal seems to be slowly coming closer and closer to the top!!! I'm going to use the vac again for 10-15 minutes after work and see what happens. I'll keep posting

Hi Guys,
Just checking in again. So far no progress.
I had bled the clutch once again and checked for leak. No leaks anywhere. After pressure bleeding, the clutch returns to normal. After 8 pumps, it goes up 70% of the way and remains there no matter how many times I pumped it.
I tried using a vacuum bleed method via the MC. The pedal would hit the floor on 1st pump. After 40-50 pumps, it regain a little pressure and remains about 40% of the way up. A lot less than the pressure bleeding.
I wonder whyyy- i'm trying to rule out everything before I go and pay for a slave job
I was at the chevy dealer today to pick up a new clutch assist spring (c5) and they happened to have a master cylinder in stock LOL Not sure how but they did. I had picked it up just in case.
thoughts?

I broke my stud and bent 1 of them while removing my cat last night LOL! called the dealer and it was $15 for the stud and $8 for the nut! Went to advance auto and got a set of m10 1.5 (4 of them) for 10 bucks phew!
After pressure bleeding the clutch from MC out of the slave(about 1 liter of fluid on my garage floor), it went back to normal but after every pump it slowly went lower and lower. It eventually settled at 70% of the way up. Not far enough for the assist spring to kick in.
I got a new c5 spring installed and I put everything back together. drove around. still the same I was able to get into all gears and no clutch slippage or grind. At this point, i was like FAWKK THIS! I'm just going to drive it as is until the pedal no longer works. It was open road - revved it to 2k RPM and launched the car went back home and parked it. Corsa exhaust sound sickkk.
Got ready for the gym. Hopped in the vette and everything is still annoying. clutch pedal still being a tard. drove it normally and half way to the gym the most amazing thing happened.
clutch pedal just popped up on its own and i mean all the way UP! 
:
the pedal is back to LIFE!
Last week was a nightmare!
i wonder if it was the pressure bleeding, launching the car, or new spring that did the trick..... no one knows!
Thank you James - Joe and everyone else for helping me with this. I'm forever grateful

Hello,
Happy Monday - just wanted to check in to give a quick update.
The pedal is still acting funny here's the new symptoms:
in the morning (after sitting for 8+ hours) - clutch pedal is all the way on top but after few pumps it would go down just low enough for the assist spring to not work. then just settles there about 80% of the way up after driving.
NEW symptoms:
- If I drive the on 1st gear on high RPM (2-3 times) from a stop, the clutch would then pop all the way up on its own. It will remain all the way up unless the car sits for a long period of time (i think 5 hours +).
Any thoughts on this?

I think the slave is faulty and sticking a little, when you get on it, and the heat builds up in the "oven" it pops into you places as the heat kinda makes it function better (in your case that is). Only thing that I can think of atm.
