hydraulic clutch problems

[PapaSmurf2k3]

Ok, i blew the slave so i replaced it, and bled it. The system would not hold pressure for an extended period of time (but none was leaking and no fluid was being lost) so i determined that the master cylinder had to have somehow blown a seal on the inside and was leaking fluid into itself. So here i am, with a new master, and new slave, and i must have bled it at least 20 times, and it wont even build pressure now, let alone hold it. No bubbles are coming out of the slave, or the airbox thing. Im pretty sure everything is hooked up right. (its not that complicated). Any suggestions? is it possible that the master is just full of air and it refuses to come out? thanks.

If it's a 240sx there is a large line bolted to the rt inner frame rail that needs to be lowered at the back or just removed and bypassed. It gets air trapped in the top of the line. Check the faq board for help.
