'88 E30, mostly stock; replaced master and slave cylinders; the connection where the clutch master line meets the slave cylinder hose is leaking like a sieve. I have disconnected the two and the threads seem to be in good shape (no cross-threading). I have reconnected the coupling to make sure they are mating squarely and torqued them down good and proper but to no avail. I can't get beyond 5 lbs of pressure on the one-man tank I use to bleed the system. What am I missing? :dunno: Any help is appreciated.
