As long as the car is driven softly it should not leak much. Like Matt says watch the oil level and change those seals when the belt is done.

If it's the crank and cams seals, there will be oil on the bottom of the oil pan. The air blows it onto the exhaust and it smokes. It may be a good idea to make sure it's leaking there and not some where else.
