Hi Chris,
There is no packing on those tubes. The reason for them is that the engine is not rigidly mounted, so there has to be slight movement. When all parts are new, elbows and tubes it is OK, but the tubes scale and flake on the swaged ends due to the heat and also the elbows suffer wear from tubes jigging around. I worked in army workshops in UK for 22 years and would have worked on Ferrets regularly in that time span and later on privately owned ones. I have built up the flaked ends on tubes with bronze welding and finished to fit the elbows snugly, not tight, so this is an easy option. That is how they were in service, always a bit of black soot around that area.
regards, Richard
