1995 Saturn SL1 Exaust smoke

The car burns a lot of oil, prb qt every 300 miles. Oil leaks out of the spark plugs. Recently tho the car has started smoking more than normal. It seems to be white smoke but sometimes has a grayish tint. It has different smell than just oil. My coolant doesn't seem to be low but there is a brown sludge in my coolant reservoir walls. The car get's hot if I'm sitting in traffic for long periods which is everyday and that's when the smoke has recently gotten way worse. If I'm constantly moving it's not bad but once my engine gets warm it starts to smoke as I accelerate and then seems to dissipate after a short period but will start right back up if I have to stop. I'm really just looking for a quick fix so I can get a new car in a couple months. Any idea's?
