Slave cylinder

Ok When i push down on the clutch i cant engage it. But if i lighty push a couple of times them push all the way down it will work some times. Could that be air in the line?????

I would try bleeding it first.
 
Is there a whirring noise when you depress and hold the clutch? If so, that's your throwout bushing/ bearing worn out.

I tried Taking off the slave and letting the bleeder out then pushing the plunger back in by hand. Then tighting it I think i just need to get some more air out that way. It just to cold ill wait till this weekend.

have someone push the clutch pedal a few pumps fully to the floor at least 3 times while its bleeding.
