WHY DOES MY 1996 GALANT BLOW OUT A HUGE CLOUD OF SMOKE WHEN I START IT THEN GOES AWAY IM USING A TON OF OIL

Blue smoke is oil. Have you checked you pcv? (Pollution control valve) it usually runs from one of the valve covers to the airfilter unit.

have the save problem with my 1990 chevy step-side most likely cause woud be as Uu mentioned above possible craced or worn piston ring.allowing oil to seep ito the combution chamber after you finish driving and car setting over night, try using cylinder conditioner at your local parts store, hope this helps.

HI do you now the color of the smoke
if engine emits white smoke its not burning the fuel
it could be water mixing with fuel = head gasket even tho you
dot have water in the oil
if engine emits black smoke - that's excessive fuel to air ration
check air filter & air inlet to see if clogged
if engine emits blue smoke - excessive oil consumption
cloud be valve seals

This is caused leaking engine valve stem seals, oil gets into the cylinders during deceleration to a stop, and then quickly burns off when you accelerate away. If it not using allot of oil just live with it, it is very expensive to repair.

Does it only blow blue smoke for a minute or so when first started? If yes, then it is most likely your valve guide seals. This is just an inconvenience not a huge problem. Check your oil level regularly and add as necessary. You probably won't even notice oil loss from this.
Thank you,

blue smoke would show a lean condition. most likely a fuel line leak between pump and tank not a pressure leak.or a check valve is allowing fuel to run back to the tank

sounds like valve seals

You have what is known as a valve guide or valve guide seal problem. as the car sits, the residual oil in the valve cover is seeping into the cylinders through a faulty seal or excessive clearance of the valve guides and is now sitting on top of the pistons, so when you start the car. it burns and goes out the tailpipe. Id recommend you take your car to a certified engine repair facility to have it checked for repair. "Valve guide seal" replacement can be done without too much headache . If the "valve guides" need to be replaced, then the cylinder head/heads must be removed. and this is a lot more costly.

sounds more like a worn turbocharger with bad seals.  Sadly this will be expensive.  Remanufactured turbos are available.  

May be just the cold weather and condensation..if it goes away thats ok i think,, if it stays thats bad.... most cars show some type of smoke or something when they are cold....mine does .. and its fine... make sure its not pure thick blue smoke., for long periods.... that means ur burning oil...make sure to check ur oil and dont ever over fill it ....
