Clutch Slipping After Master Cylinder Replacement

2003 911 Turbo, 6-Speed, Clutch has about 11k miles on it.


 

About 2 months ago, I started having minor issues with the clutch pedal not returning consistently. Took the car to my local Indy and they replaced the Master Cylinder (black master cylinder instead of green btw?)

 

When I got the car back, the clutch was extremely stiff and the release point was extremely high, but it drove fine and had no slipping under full power.

 

Fast forward about a month, I haven’t driven the car at all and got in it to drive a few hours away, and the pedal is back to being extremely sticky and the car is slipping in any gear under the slightest load. Pretty much not drive-able the slip is so bad.

 

Pentosin reservoir is completely full, and no signs of any fluid leak at the master or under the car anywhere.

 

Any suggestions on where to start?

Welcome to RennTech :welcomeani:

Unfortunately, your original problem mirrors common complaints when a clutch is on the way out.  I would do two things: Rebleed the clutch hydraulic system and see what happens, if that doesn't do it, it may very well be clutch time.
