Clutch master cylinder failing

Well after much struggle with bleeding the fluid through the system i took a look at my new gutted master cylinder and noticed that the feed hose hole from the fluid reservouir almost perfectly matches up with the back of the piston, in my car however i had the pushrod screwed in with zero slack on the piston so i losened it up until the pushrod moved freely, after i did that i took my mityvac brake bleeder and attacthed it to the bleed screw and VOILA i have break fluid coming through,
I did this for a while and flushed 2 liters of fluid through the system, after i did this i was still having the pedal drop all the way to the floor, so i removed the slave cylinder and pumped it until i was getting a nice consistant flow of brake fluid, as soon as i got that(before i reatached the slave) i ran the mityvac on that and got all the remaining air bubbles out.....
Onto re-instalation, since my slave cylinder came completely out of the bell-housing i had to make sure i got the pushrod in the right spot so if you look through the service hole you can see a little dimple where the pushrod fits into, so i popped it in there and bolted the unit back on, went back into the car and i had a PERFECT pedal..
Testing: I turn on the car and i push in the pedal( had a nice firmness to it) and proceed to put the car into gear ****GRINDING NOiSE****.. I turn of the car because i know that the clutch isn't engaging, i check back at the slave cylinder and notice that the pushrod popped out of the dimple so i reinstall it making sure i stayed in the dimple while i bolted it on
--Turn on the car again, push in the clutch slowly inching the shifter into first and it slid right in with no problems!!!
I owe my thanks to you guys for providing my with great tips
Now lets open up a couple of cold ones!!!

and then i was stupid enough to not tighten the bleed screw and when i parked it in my garrage.....
an hour later, turn on the car push in the clutch and SLAM right to the floor :-p i get to do the whole process over again within 15 minutes so i can get to school...
so before i had a perfect pedal, now i have a fairly sloppy pedal so i have to start over tomorow
