This is a great method to use if you have room between the cylinders for the rings, which most engnes do, but some don't.
That method is the commonly used in the building of the hot section in a turbine engine . We call them the e-ring . Good ideal!

It definatly is not a gas filled ring.
As soon a we got the tuneup right the gas filled ring failed.
But the solid ring did not.
Machining is also very simple.
