Can't seem to figure out where the oil went, just assuming that it is burning off in the engine.
If the car was not maintained properly for the past 130,000 miles then it could be other things other than a leaky valve cover gasket. But that'* a good place to start and, of course, the cheapest. Next, you could start taking the spark plugs out of each cylinder (maybe it'* time replace them anyway) and look at the condition of each plug. Is there an oily coating on any of the plugs??? After that it starts to get costly. One, or more, of the Valve Stem Seals could be leaking and you would never see any oil on the ground. It'* just being burned up in the engine. Baciallly you're adding a quart of oil in between oil changes, right? Two quarts, between oil changes??? Whatever! Anyway, adding a quart of oil now and then is still cheaper than rebuilding the entire engine just to consume less oil. Also, it might be a good idea to clean the entire engine bay with an Engine Degreaser.
Just follow the directions on the can. DON'T use a pressure washer on the engine.
This should temporarily get rid of your "Burning Oil" smell until you find The Leak.
