Make sure oil level is OK, make sure oil light comes on when the ignition key is turned to the on position engine not running and goes out when the engine starts and runs. It could be many things, unfortunately and without hearing the noise first hand or being able to do some basic diagnostic tests or be able to drive the car, its hard to say what the source of the noise may be. It may not be safe to drive or may do more damage (hopefully it's nothing to be concerned about) but get it checked out by a mechanic to put your mind at ease!
