However a few movements back and forth of the cage and it goes all tight again. So I back off the bolt and it’s nice and springy again. But again a few movements back and forth of the cage and it goes all tight.
It’s definitely being caused by the clutch
The solution here may well also be Loctite - disassembly would've significantly reduced the effectiveness of any factory compound. Assuming of course there isn't a proper locknut or something you've missed. You can tell I know fuck-all about derailer clutches

Hmm I've looked at a few guides to service shimano clutches, none of them mention locktite. There was no locktite breaking crack when I disassembled either. There's a roller bearing that sits on the outside of the p-axle, that the clutch pushes down on when engaged. I assume it isn't working properly and that's why it is tightening. I just don't know what has caused it to stop working.

It’s definitely being caused by the clutch because when I remove the clutch mechanism it’s not happening and remains nice and springy no matter how many times I move it back and forth
