Static Oil Leak Checking

I wanted to Dyno my motor, with about 50% of the reason being to check for leaks before installing in my freshly painted car. Now I'm feeling cheap, well at least my bank acct is.
So has anyone ever put oil in their pan then hung it off a hoist at an angle for a few hrs to see if anything can weep thru? Front and rear. I was thinking this might give some kind of indication if pan gaskets or rear seal is a leaker.
Anyone tryed this? Dumb idea?
