Do you have any pictures of the various bits and pieces that you could post up? Sometimes pretty small differences in thickness or tolerance can have a big impact.

How did the bleeding go? Were you able to get a constant stream of fluid with no bubbles? If not, then I'd definitely look into the clutch master cyl. If you were, and you said that you can see the clutch slave cyl moving the fork when you press the clutch, then that points towards some other fault. How much does the slave cyl move? At least an inch or so?  If so, I'd tend to focus more on the clutch, pressure plate, clutch fork, or some other fault than on the hydraulics in this case. The fact that you said its moving but that there is basically no resistance makes me think that something in the stack-up between the clutch slave cyl and the pressure plate isn't correct. Bent clutch fork, incorrect throw-out bearing like you had said, or bad pressure plate seem like the likely contenders, although I guess its possible that the clutch slave itself is an incorrect part

Post up a picture of the trans input shaft, focusing on the smooth area that slides inside the pilot bearing in the end of the e-shaft, and on the splines that the clutch rides on.

Try pushing down all of the pressure plate teeth to make sure that you can see some movement of the friction surface inside the pressure plate. I'd look at each one individually, and then if you have a vice or hefty clamp, try to rig up something that would allow you to press them all to make sure the friction surface moves in the direction that would be away from the flywheel when the teeth are pressed towards the flywheel.

Inspect the clutch carefully, looking for scrapes, indentations, or other signs of damage. Its possible for something to have broken and jammed underneath the pressure plate, but it should have left a mark. Does the clutch slide freely along the splines of the trans input shaft? The clutch wasn't installed backwards, was it?

Does the pilot bearing in the hole in the end of the e-shaft look ok?

I will get some pictures in a little bit. bleeding went as well as it should, i bled it a good 10 more times after no more bubbles had leaked out just to be sure. The fork moves about an inch or maybe more, and doesnt appear to be bent but I'll take it off to get a better look.

At first glance, nothing seemed wrong with the transmission side. No marks on the bell housing, input shaft splines all looked good, throwout moves freely on the shaft and spins nicely. Also no gear oil in the bell housing which is a plus!

Yesterday was a long day at work and I was falling asleep under the car and didn't look at the pressure plate. I've got the next couple days off so after I eat something I'm going back out there and will take some pictures of the trans and clutch assembly. I'll post them up in a few hours

FCwidman:
Having trouble getting pics to load on my computer, any way to do it through an iPhone?


Well apparently I'm my 4 years in auto engineering school I didn't learn how to read because I put the T/M side of the clutch disk towards the engine. Gonna go over everything just to be sure but I'm 95% sure that's gonna cause no interaction between pressure plate and clutch
No odd wear marks or anything broken or bent so far

toplessFC3Sman:
Thats a good sign -  if the clutch disk friction surface is not centered on the splined hub when viewed from the side (and usually they aren't, for packaging the sprung clutch hub, spline etc up against the relatively flat flywheel), it could be constantly pressed into either the flywheel or pressure plate friction surface, so even if the clutch hydraulics, fork, throw-out bearing & pressure plate were working perfectly, the engine would still spin the trans.

While you're in there, it doesn't hurt to look over everything, but its promising that you found something.

FCwidman:
Trans isn't back in, clutch works great! Just puttin the exhaust back on and off for a drive I go. Might make it to Woodward tonight if all goes well.

Hopefully this fixed all my vibration and noise issues that were the original issues I was concerned with
