Have an update for you all:

So after several attempts at reverse bleeding, (Using a MityVac, applying vacuum to the top of CMS and pumping clutch) I still was losing pressure after driving for short periods of time.

I was about to pull the trigger on a new CMC, and before I did so I wanted to double check there were no leaks or out of the ordinary issues that I was not seeing.

Everytime I would pump the clutch, I could hear a little swoosh as the pedal returned to the top. I noticed the CMC piston was coming out a lot, and when being depressed, would pull a tiny bit of air back in the lines.

This is when I decided to remove almost all play by adjusting the top bump stop point further forward. This left around 1/4 of an inch of play up top, and there was no more noise when engaging.

So far it has been 3 days, lots of spirited driving, and no issues!

I think that since the new clutch install, the engagement point is a lot lower than the oem causing the CMC to pull air back into the system every time it over extended.
