There are a lot of things on an engine that can leak oil when running. Mostly a blown gasket. Check the valve cover gasket. That is the cover on the top of the engine.

Another possibility is the oil pressure switch for the warning light. There is full engine oil pressure at that switch, so if bad it will cause a very bad oil leak whenever the engine is running.
