My guess would be bad valve seals or one or more worn valve guides.

Well, what color smoke? If it's black smoke, you're running rich , if it's white smoke you're burning oil. Black smoke can be cause by anything that will cause the car to run rich. faulty O2 sensor, sticking injector, bad plugs, faulty ignition system. White smoke can be caused by worn rings , worn valve seals, anything that will allow oil into the combustion chamber. How much miles you have on the car?
