What happens if you turn on an engine without oil?

Bearing journals do not drain empty when the engine sits, surface tension, or capillary effect keeps oil in the clearance space of the bearing, even in engines that have sat for months, and that oil film will float the bearing journal before the electric starter even makes a complete turn during the start.
Why does my car leak oil when I stop driving?
Once you stop driving and your car is parked, a car’s engine block and the head will be hot from the heat generated while driving. The metal components expand when they’re heated, which in turn, puts pressure on the seals and gaskets. The engine seals and gaskets are meant to prevent an oil leakage.
