My son's car has been slowly dripping oil. Then after it sitting for an hour had a big puddle where he was parked. Passenger side.

Hi Stacy,

More than likely this is the front crankshaft seal. Obviously without seeing the exact location, this seal makes the most sense on the passenger side of the vehicle for a large amount of engine oil to be left in that little amount of time.

However, here is a guide that talks about the most common causes and covers this part:

Please let me know if you are able to see the general area or part that the oil is coming from. That will help narrow this down or confirm the front crank seal. Thanks.
