I would highly recommend dropping the pan. Something clogging the oil pickup screen such as some foil from an oil container, could cause these symptoms. The clogged screen would also cause the oil pump to cavitate which may have caused the leak.

Agreed. If the oil light illumination accompanies with engine clanking there`s no need to test its function, or at least it`s not top priority. You can easily cause permanent damage to the engine running it at low pressure.
