The benefit of the transfer pump is you can provide a continues stream of smoke under pressure much easier than the Professor Scotty method.
Often there are crankcase air leaks and cracked or leaking valve covers and you need to remove the oil fill cap until smoke is coming out of the oil fill hole, then recap the crankcase. Then watch carefully for smoke to escape. You might get pretty winded trying to fill the crankcase and keep everything under pressure. Kind of like blowing up an air raft or mattress, you will not last long.
Professor Scotty's method is good for large leaks, but the smaller leaks are better found with a fixed/continuous pressure.
