in my 99 eclipse gs-t I recently swapped out my old leaking clutch slave cylinder with a brand new one. I checked under the car a few weeks later and it seems like the leak is still there. Also in the clutch fluid resevor the fluid has changes from a clearish golden color to a cloudy grey color.

Does anyone know how to get this leak to stop and how the fuild could of changed color like that? even with the old leaking part it didn't change clolors.

 

Did you change out your master along with the slave? It's often a good rule of thumb to do both at the same time.
Anyway, did you flush the system when you replaced the slave? If not, there's one fix.

 

Flush the old clutch fluid out with some new fresh fluid. Get you some brake cleaner and spray everything off afterwards. Also spray off and wip down you both your clutch, And brake resivor. Common leak on the master cylinder is behind the pedle so check there as well. DO NOT spray and rubber with brake cleaner because it will dry it up Use WD-40.
