Great run, great whine!
As to the smokestack/safety-valve, it looks
to need some tightening or perhaps a good
sealing washer between the SV screw 'head'
and the inside of the stack. You should see
some leakage but certainly less than seen.
Not a big deal, everyone that has been buying
and running Empires for a while has done it.
Congrats on the transplant,
