There is a leak that needs to be repaired
Am I looking at an external oil pump or an oil cooler on the bottom of the engine? on 2001 Infiniti QX4
There might be an external cooler and that is one of many places that a leak can come from. You'll need to have your vehcile looked at from underneath to help determine where the leak may be coming from, and even then, some cleaning may ne necessary to pinpoint the problem area.
