Brake fluid is cheap, and i used about 0,3litre fluid for my clutch. I would try again and opening it much more ... fit the wrench the other way, so you can loosen as much as you want without removing the hose.

Ok will opening it to much not cause an issue with air coming though the threads of the bleeder?
I'm going to give it a shot again
But any other advice is still appreciated !

It will suck back in using path of least resistance, which will be the open bleeder, not the threads.
If you put a hose on the bleeder, it will suck back fluid from the hose, not air, through the bleeder.
But if you gravity bleed (which is the recommendation from authorities as distinguished as Billman), instead of pumping pedal, there won't be any suction anyway.
Are you gravity bleeding?

A gravity bleed alone will not really replace all the fluid in the slave as the fluid entry is close to the bleed.
Even when you have the slave / bleed pointing upwards.
Besides, if you can unbolt the slave and have it in your hands without the piston trying to pop out, I would say the piston is not moving freely.
The spring behind the piston is strong enough to push the piston out.
My method is to use the slave as a pump.
Attach clear tube to bleeder, open bleeder with wrench and close it by hand, unbolt slave, hold it up with one hand while you keep the piston where it is, open bleeder by (other) hand, gravity bleed for a little bit, then push the piston slowly ALL the way in (the piston goes in further than you think) with the bleeder still open, you will see dirty fluid in the tube, when the piston is all the way in end close bleeder by hand and let the piston come out slowly (but not all the way), use a rubber band or something to prevent the piston from falling out, refill the reservoir and repeat until the flow through the clear tube is always clean & bubble free.
You can do 3 pumps when the reservoir is full before running the risk to suck in air.
Don't use any sharp thing (like a screwdriver) to push the piston in as the cup where the push rod goes in needs to stay smooth.

How does the clutch feel though? It's possible your getting air in the line from the hose connection on the bleed valve or from the threads on the bleed valve, making it look like air is coming out...
