Blue smoke is normally worn valve guides or piston rings letting oil into the combustion chamber and thus out the exhaust, whereas white smoke is normally a blown headgasket or coolant somehow getting into the combustion chamber.

Not necessarily, it could just be some worn valve guides. If you get a compression test kit with a compressed air valve hold you can replace them on the car.
Edit: pull your spark plugs and let us know what they look like, make sure you mark which one came out of which cylinder as you'll need to know where the problem is exactly.

I8ASaleen, I think you are confusing valve guides for valve seals. Seals can get old and harden and leak, and they can be replaced on the car.
Valve guides however cannot be replaced with the cylinder heads still on the motor or the valves still in the cylinder heads. Replacing valve guides or putting in guide liners requires machine work. Guides can become worn and get excessive play, causing the valve stem to rock back and forth and let oil by the seal.
