Why does my clutch keep getting air in the system?

[DailyDriver]

I'll bleed the slave cylinder & it's fine for about a week. After that the pedal gets soft & will only disengage the clutch with me practically pushing it through the floor.

Here's the crazy part...I have NO loss of fluid. So if it's leaking somewhere I sure as hell can't find it!

Slave cylinder going bad...it's only about 3 years old???

Sounds like a Master cyl that is blowing past the seals and/or weak seals.

Agreed.

I forgot to mention I just changed the clutch master cylinder this past weekend. I was hoping that was the culprit b/c it's easy to change & was free (lifetime warranty). But the same problem is occuring.

Not saying it's your problem but i've seen several RBV slave cylinders do that in the past. I never learn from my mistakes because the last time it started happening to me personally I let it go and kept bleeding it for like 6 months then while driving during a snow storm it decided to "pop" on me.

I finally found the problem. It's a slow leak at the bleeder valve on the slave.
