Did you really mean to say, "on the exhaust pipe"? That would imply oil is dripping onto it from the engine, and that would indeed be caused by a leaking seal, most commonly a valve cover gasket. You'll see and smell the smoke, but it won't be blue.

If you're seeing blue smoke from the tail pipe, that is a sign of burning oil in the engine. Typical causes are worn valve guide seals, worn piston rings, an inoperative PCV system, and oil that has been diluted with gas.
