how do you do your mityvac bleeding? can you please describe?
yes, it's like a bench bleed but while the everything is on the car and no need for a remote bleeder. The line you create plugged into the spark plug boot acts as just that.
I think I've posted this one a few times, but sure.
I use a Mityvac with the big flat attachment (the one that looks like the end of a plunger in this picture):
I drop that whole shebang into the master cylinder and suck up a couple pumps worth of fluid to fill the lines (so I don't push air when I release pressure) and then push it down so that it seals to top of the bore that the reservoir seals to. I this picture you can see where the clamp secures the reservoir. This the bore that sticks up that you seal the Mityvac against. Obviously you do this with the reservoir installed and full of fluid:
I then pump the Mityvac up to about 15" of vacuum and let it sit for 10-15 minutes. Then bleed it off slowly (don't let it push air back into the hose). Remove it from the master and pump the pedal a few times, then repeat as necessary. I generally complete it in 2-3 cycles. This takes maybe 30-45 minutes to complete, but is only like 2 minutes of actual work (unless you really want to stare at it while it sits and draws vacuum).
I have done upwards of 20 systems on FCs and FDs this way and it works 100% of the time. Rock hard pedal on every single one of them and I've never had any of them with all of the random "my T56 won't shift at WOT" issues. Careful routing of the hose away from exhaust helps this also. This method won't work if you have the clutch master tied off of the brake master, but I think that's a bad idea.
