    Noone will know from that description...

    Start checking gaskets. Get under the car and trace the leak.

    Put it up on ramps/lift and clean all the old oil off the underside. Then let it run for 15 min and see if you can see where the leak is coming from. If it hasn't leaked yet let it run longer. If it has leaked n you still can't find it the wipe it off again and let it run for 5 min and try again

    The bottom cradle will hold oil, and leak onto the ground when parked at a slight angle. Have a look at the oil pressure sending unit, valve cover gaskets, crank seal...all 3 will cause a decent puddle.

    Gm cars always have bad valve cover gaskets. So check that. And like stated, oil sending units leak pretty bad. How many miles do u have? Also like stated u need to clean under ur car real REAL good in order to see where its coming from. If u have any connections and can get it on a lift, that would be the best bet
