Basically you pressurise the cylinder with an airline, shut the airline off and then measure the drop in pressure over a period of time - 5-10% is good, over 30% bad! The advantage is that you can also get an idea when you do that of where it is leaking from - e.g. hissing from exhaust manifold = dodgy sealing ex valve which may mean valve train issues, bad seats blowing by etc etc.

Lots on the internet about it - not sure what the exact figures on the RV8 are.
 
Not sure that's justified but thanks Sam. All just bits I've picked up along the way.

Engine out on Cobra today - now that's scary!
