Seeing smoke from the tailpipe usually means your engine is leaking something thru a gasket. There are multiple gaskets as well that could be leaking. ou have to determine what fluid id leaking (coolant or oil (or both)). The color ofthe smoke helps tell what type of fluid is leaking. White - coolant / blue/black - oil.
Coolant - usually leaks thru the intake gasket which is VERY VERY common on Alero's. They now have a better grade intake gasket available. I just replaced mine on my 99 (under warranty thankfully). It costs around $500.
Oil - you could be burning oil from worn piston rings, crankshaft seal, gasket, cracked part or head gasket (where it mixes with coolant).
To find out what is leaking - check the level of coolant in the reservoir and monitor the level over the course of a week or two. If it gets lower, you are leaking coolant. Same for oil. Get an oil change and then check the level every week to see if you are gradually getting lower. you can also have a shop do a compression test of the engine. Hope this helps.
