Yes, but it could be air in it still.

No a new MC will be fine with this. An old MC will fail.

Hydrolic Clutches suck to bleed. I had a chevy Nova that took me 6 months to
get all the air out. The worst part about it was it was winter, I live in
Boston and this was done on the street with traffic going by:( I bought a
new MC and SC and ended spending 45 minutes every saturday (sometimes in
heavy snow) trying to get it right. I got a Motive Power bleeder on Ebay for
$30. It took 10 minutes and I never had any problems after. On my 100q I
bled the entire system in 40 minutes when I first got it.
