Please Help!!

So just replaced my CDV valve with the aftermarket one and lost fluid through the hose while doing so. The new valve is in place and i have tried to manually bleed the clutch but dont know if i am doing it right. I cant get the clutch to build anymore pressure back up it just goes straight to the flooer

We pumped it three times to the floor

then i loosned the bleed screw and let some fluid out and tightend it back

Did this 10 times and still nothing.

How do you properly do it....

DOES THE CAR NEED TO BE RUNNING?
DOES THE TOP NEED TO BE OFF THE BRAKE FLUID HOLDER?

Im losing sunlight please help

Make sure there is fluid in the reservoir at all times. The procedure is to pump the clutch and then gently press to floor as someone bleeds from underneath. The bleeding part is somewhat difficult due to access but you need to time the bleed with pressing the clutch to the floor, then shut bleeder, pump clutch and repeat. It will take some time if there is a lot of air in the system. Car doesn't need to be running and leave the cap off reservoir until done.

Not installed correctly, make sure it's lined up right and tight. Which end is fluid leaking from?
