That would require fixing / replaceing the VALVE SEALS in the heads.
Need more info such as the year, engine size and what color smoke.
the valve stem seals are probably dried up and leaking when engine is at rest
blown piston rings or valves in the cylinder head not seating properly
Worn valve guides? New answer : Worn valve guides WILL cause some what of a rough idle and engine would smoke at all times. If engine smokes at start up only and then quites then your problem would be the VALVE SEALS.
sounds like the valve seals are leaking oil into the cylinders when engine is stopped not a big deal for a car that age
Is this a trick question?? This is wat i sound lik: "why does my cars EXHAUST smell like EXHAUS?its also SMOKES at START UP... Ima leave that as that
You are probably leaking some kind of fluid on either your exhaust or your block. If i were you i would clean your engine really well then start it up and look for the wet spot. That will tell you what is leaking.
If you notice it when you first start the engine, it could be bad valve seals and/or loose guides.
valve seals and or guides bad

That is fine. Its just the hot exhaust meeting the cold air. When it smokes on warm days on start up, then there is a problem, and if it does that then its probably the injectors going bad.
If the engine is four-cycle, the valve seals may be worn, causing a small amount of oil to seep into the piston cylinder or combustion chamber. If it is two-cycle, the oil/fuel mix may have a little too much oil.
