Clutch problem II.
Thank you to the guys who suggested I bleed my clutch's master cylinder. Now my next question is...How do I do that? Is it like bleeding the brakes wheel cylinders or completely different? Is there a bleed valve on the clutch MC under the hood or is the valve under the car?

Bleeding the clutch master cylinder is normally a two step process.
First is to bench bleed it which means with the MC held in a vice, the front and rear output ports can either be capped-off or adapters put into the ports with short hoses routing the fluid back to the bowl....I have seen it done both ways. The MC plunger is pressed-in only a short amount of travel to get the air out pistons.
Second is done with it on the car and using the bleeder screw on the slave cylinder to bleed the entire system. I believe that the slave should be taken off its mounting as the bleeder screw is on the bottom. So getting the air out is better done with the bleeder screw on top and even tilted a bit so that the air goes out the highest point. Requires two people to do this or a hand-held vacuum (MightyVac) can be used or a one-man bleeder setup.
