Our engine was just overhauled professionally. We were told to hand turn the engine or with the starter only without compression to fill the engine crankshaft and valves. I just primed the oil pump and am beginning to try to get oil throughout the whole engine. My question is how long will it take before that oil gets around? I want to make sure that it is working properly before the engine fires up. Any ideas?

Five minutes or less. The oil pump creates a high volume. When we build a new engine, we use plenty of assembly lube to protect the bearings, so we don't worry much about start up.

Did the person who assembled the engine use assembly lube and if so which one? How long has it been that the engine was assembled? Some assembly lubes expect the engine to be put in service shortly after assembly, others can go for longer. What you want to avoid is a dry start up where surfaces are rubbing together without lubricant separation. Did the oil pressure come up to operating pressure when you were turning the engine over without compression?

When you get oil pressure, the bearings should be receiving oil. As Oldad said, how well your engine is protected in the first startup depends upon the assembly lube used. Tom
