One will eventally over time be ample to quickly assess if an engine is satisfactory or not. Any thoughts - what pressure will engine shut off ( MW pump on mine )

One standard measuring method is to get a 30 gallon trash bag and observe how much it inflates over 1 minute.

Pressurizing the crankcase on any engine is very bad, its a quick way to blow out many oil seals.
