It's most likely worn valve stem guides and valve stem seals. Can also be worn piston rings and if the engine has a turbo, leaking turbo oil seals. Another thing is excessive idling.

I would suspect the valve stem guides and seals. That's about the only place for oil to leak into the exhaust passages. Some engines don't have seals on the exhaust valve stems, so it's possible that this is normal for your engine.

Blown piston rings?
Scored cylinder wall?
Hole in the piston?
Could be unburned fuel not oil?
Leaking head gasket?
Valve seals?
