Clutch Issues - post bath

[Vombil]

So my 6cyl WB van was super greasy. I gave it a really good soaking with the old girls fang dangle Karcher commercial grade pressure cleaner. I tried to start and run it after the bath but it didnt kick so I left it to dry out for a few days.

Started and engine runs fine but the clutch wont disengage now! I pumped the pedal a few times and played with adjustment... nothing.

So I took inspection cover off and saw that the clutch plate was rusted to the flywheel. I flicked it off but now I think I may have stretched the cable (this was already adjusted way out-max). Also when I get my GF to dip the clutch I can see the clutch plate move only half a mm off the flywheel and the clutch plate itself looks to be splitting in half when dipped(you can see the shim thing in the middle).

Has anyone had this happen before? any tips? Reckon its worth trying a new cable before a new clutch kit?

thanks in advance for any suggestions

update: im headed out into the dark to see if clutch plate is also rusted to the pressure plate!

update: was rusted to the pressure plate as well!!! Ill fire it up in the morning and see what happens... fingers crossed
