I get all the fun stuff...

The current patient is a 93 RT/TT that came in for a clutch hydraulic issue. Obvious master cylinder bypass, pedal to the floor intermittently, sometimes it would work... Slave leaking like a sieve as well.

I replaced the master, rebuilt the slave, bled the system, and I find I still have other issues... When the engine is not running, the pedal feels good, when you start the engine and try to shift, the clutch is dragging. If you apply some pressure to the shifter and drag a synchro a little, you will feel something cut loose in the clutch, the pedal relaxes slightly under your foot, and the drag is gone. From there you can shift to any gear just fine without any clutch drag. As soon as you let the clutch out and push it back down, the whole scenario repeats. It's absolutely consistent and repeatable.

I guess I'll report back when exploratory surgery explains it all... After 30+ years of turning wrenches, You start the think you've seen all the strange stuff they can throw at you... Guess not.

Here's a short vid of the throwout fork and slave as it's happening. Watch as I push the clutch in, then wait a second or more, and push on the shifter to drag a synchro. As soon as I do, the fork moves out slightly as the clutch releases.

Anyone ever seen some crap like this before...?

hmm I wonder if there are some diaphragm springs that are bent up or broken? not pivoting correctly.

I don't know... It's damn odd. The only thing I can think of that I'm changing in the clutch area by loading a synchro, is that it's putting a torsional load on the disc hub... What's happening from there I haven't explained yet
