Think I need one, so thinking about quick/dirty improvisations.
How about steam? Easier to generate and self-pressurising. Maybe less visible.
Main risk I can think of would be condensation pooling in a cylinder giving hydro-lock damage.
There's also corrosion potential if I didn't get the thing running in a reasonable time and it sat with condensation in it, but then there's always a bit of blowby condensate anyway.
