Hopefully someone on here will be able to read this and give me some help, I'm stumped.

Several weeks ago I burned out my clutch. Replaced the Pressure Plate and Disc with a Perfection part, put everything back together with fresh fluid and tried to drive. Clutch would not disengage at this point. Ok so we pulled the slave and replaced that, put new tranny fluid in, I replaced the hydraulic line from the Master to the Slave. New Brake fluid has been put in, Master Cylinder bled and I got a friend to help gravity bleed the rest. The fluid comes out a little milky, but for the first time we have been able to drive the truck in weeks.

We get good pressure after pumping the pedal a bunch and take it on the road. Driving a few miles the pressure suddenly drops from the clutch and we cannot shift gears. Pump the pedal about 50 - 100 times and it goes into gear, bring it back to the house and park. I'm at a loss as to what's what here.

Clutch master cyl drawing air ?

No air being drawn that I can tell. New O-rings on both sides of the hydraulic line that got replaced. Piston barely pushes in on the Master cylinder. I have good pressure, it's just not keeping it.

Ok so I setup a bottle and attached a hose to the bleed screw on the slave cylinder. Kept getting air everytime we cracked the bleed screw. Went through an entire bottle of DOT 3, but still get air bubbles coming. Could there be air getting into the system, and if so, from where?

Master Cylinder still appears to be good. There is almost no movement on the piston. I'm stumped again.
