Oil cooler removal: return line gland nut (4 cyl)

[Flying Custard]

So I'm hauling my engine out ready for sprag sorting. All is going well, except the return line gland/compression nut, on the cooler.

I'm holding the inner 'nut' (part of the union), and undoing the comp nut - but the oil line is turning with it, and so is getting twisted.
Now I assume line and comp nut should be free of each other, and mine is just corroded up, but before I cut the sucker off I thought I'd ask you guys to confirm/deny...

Well that's sorted with some penetrating oil, though could've done with 3 arms (might be worth moving next to Sellafield)*.

Onto the headers. These can't ever have come off, and the yrs by the sea have made the studs/nuts (?) unrecognizeable rust blobs. Nice.
