I presuming this will get progressively worse. Is this something that
can be repaired or will it be time for a new cylinder soon.



You simply need to remake that joint. You don't even need to fully drain
down, just the coil. You should be able to shut off its feed from the
header tank, and if you're lucky there will be a drain cock somewhere.



Thanks for the advice but it's actually leaking around the coupling
that's integral to the cylinder, i.e. the bit that comes pre-fitted to
cylinder rather rather than compression joint.
