Make sure your bushings are good (clutch rod ... its probably new in your case ... and pedal box main shaft bushings). When bleeding the system (bleeder valve or not ... I've had both) here's how I do it: Unclip the slave from the bellhousing and let it hang from the line. Disconnect the clutch master cylinder rod from the pedal linkage (at the spot of the infamous bushing). Remove the reservoir cap and rubber diaphram. Cycle the slave slowliy by hand about 10 times and all the air should go up the line and out through the reservoir. You can even remove the whole thing (master, line and slave) as an assembly and do it on the bench (keeping everything from the slave going "uphill"), but it's not necessary. After all that, you may need to re-index the lever that is attached to the main pedal box shaft due to parts differences. It is splined (kind of) to the shaft, so you have to pry it off. Of course you want as little "free play" as possible before the rod starts getting pushed in, but don't have it where it is already pushing the master cylinder rod in with the pedal all the way out as that will cause a port in the master to be blocked (which is why I always disconnect the linkage before bleeding). Cheers!
