Hello Tony,
If you're interested in just a quick go/no go leak test its dead easy to fabricate something from an air fitting and an old spark plug shell and look/listen for bubbles in the coolant or air leakage from the exhaust pipe or carburettor.
This is what we do 99% of the time in the professional environment, after all, if its leaking enough to affect the running of the engine, it doesn't really matter exactly how much it's leaking. In this country (at least) there's also the TK cylinder leakage tester (and imitators) where you aspirate a sample of the 'air' above the coolant through a coloured test solution and look for a colour change of the solution caused by exhaust gases escaping through the coolant.
