What would cause a '91 honda civic dx to burn white smoke from the exaust&or what...
...seems like under the engine? It only releases the smoke when I throttle (give it gas). Also, the engine sounds alot "deeper/slower", not the pep that it used to have before this began to happen.

Your PCV (Positive Crankcase Ventalation) Valve may be leaking . Or it could be the hose going between it and the air intake manifold.
With it smoking when the pedal is increased may be a sign of worn piston rings or worn valve seals.
The combustion chamber maybe leaking some of it's explosed gas/vapor, into the crank case (oil cavities/chambers)
Does it have high mileage?
With a leaking PCV , it acts like a vacuum leak.
Normally the white smog is recycled back in to the intake by vacuum , to be re-burned off and sent through the muffler.
Any leaks behind the mass air flow sensor is un-registered air (to the Computer) going to the cylinders.
This leak has a leaning effect (added heat) to the combustion chamber/mixtures.
Simple fix : PCV @$10 (quailty....Don't by the cheap $3 ones) , Valve cover grommit @$3 , And a rubber hose @ $1.25 a foot'.
Pull them off the engine (simple), and take them to the counter at the parts store.
