Good observation...

How did the flywheel look? 

If the clutch is acting like it is partially engaged even with the foot off the clutch pedal - there must be something wrong with the installation. You might try unbolting the clutch slave from the housing to see if anything changes. If not, then there has to be a mechanical defect inside.

Just trying to guess what might cause this, I thought of the 1st gear synchro...  or maybe the flywheel failed and the dual mass plate may have separated changing the thickness of the flywheel?  These are pure speculations trying to find something to explain the symptoms....

If you are replacing the throwout bearing, you might also replace the guide tube. Also check the rear main seal since it is right there. you might as well take care of these little things since you have the transmission out.

Can't see the photo of the shift fork....  

Ok replaced Pressure plate clutch guide sleeve put new oil in transmission
 
bled the clutch
 
then the fun started
 
it is slipping the clutch without pushing the pedal getting the pressure plate hot like something is locking up inside the transmission
but if we start it in gear it works just fine just like before 
it is only when we start it in neutral


essentially same as before but she runs fine thru the gears from a dead start now we are really baffled any ideas?

and we are dropping it tomorrow gonna look inside see if the clutch release fork or the throw out bearing are the cause or anything else in there 

I spoke to a Mini Tech at Mini USA he said to read some articles he sent me

honestly we are stumped on this one its time to start taking S*** apart
I would think that the wrong fluid can cause difficulty shifting as in the gears catching / grinding when shifting but I can't see how it could prevent you from shifting...  

Curious to know what you find when you drop the transmission....

Im at wits end here
It still sounds like an issue with the clutch hydraulic system but I am out of ideas...  

If the clutch hydraulic lines and the clutch master and slave have all been checked out, not sure where else to look.

It 'may be' possible there might be an issue with the clutch fork or pressure plate, but it seems unlikely with only 13k on the clutch...

Bleeding the clutch master/slave cylinders:
a. remove slave cylinder from transmission housing
b. compress slave using this tool or similar
c. open valve on slave and bleed, close valve when done
d. remove slave compression tool
e. bleed system again
f. re-install slave onto transmission housing


We put in a new MC power bled the system and still feels mushy the pedal does stay up but the car still wont go into gear like the shaft on the slave is not pushing out far enough 

thoughts?

we are going to put in a new Master Cylinder in today 


it doesnt seem that the shaft is extending far enough and feels mushy so going to power bleed the system again today



I would have never figured this could be so hard to bleed a clutch system

As for the reason the clutch is not fully releasing, it can be the slave or maybe the shift lever / fork that presses against the throwout bearing might be bent...  Lets hope it is the slave.

power bled the slave and it is doing the same thing the clutch still feels mushy like there is still air in the system and the slave is not pushing the lever far enough to engage or disengage the clutch while the car is on, the next we are going to do is replace the master cylinder under the dash  any thoughts?

We are installing that today the better nor reconditioned part will be in today , My mechanic seems to think that is the problem.

there are no weird noises coming from the gearbox of shifter 

to be honest im stumped these things are not that hard to figure out , well at least I thought they werent.

In your humble opinion what do you think it could be?
