My 90 302 is burning oil, it has new valve cover gaskets and no present leak (except a slight drip on the pan). Where is it going?

We need a little more information here.
1. How much oil are you loosing and how often?
2. When is the last time you changed your oil?
3. Are there any oil spots on your driveway?
4. Was this a sudden loss of oil, or a gradual loss?
Problems could be any number of things, including piston rings, leaking oil pan gasket, leaking oil pan or drain plug, oil filter not screwed on tight enough, or cross-threaded...
If your exhaust is heavy with smoke, you're burning oil.
Just some thoughts.

Well, I did an oil change in February and there are oil spots on the driveway. The truck was down about half a quart yesterday and seems okay today. There is also a burning smell coming from the engine after I turn it off. It'll smell if I drive it for alonger than 20 minutes. I puts out a slight whiteish smoke.

Alright bro, here is what I would do:
First, get a couple cans of Gunk engine degreaser...the gel type or foam. Next, buy a gallon of Lucas Oil. Drive with your heater on full blast (this helps cool the engine) to the NEAREST car wash. Wait a while for engine to cool down. Cover the distributor with a plastic bag...making sure everything has cooled down first. Spray that Gunk all over the side of the driver side of the engine, especially where the oil filter is, and down from there. Get underneath the Bronco and spray Gunk all over the oil pan and anywhere you see oil. Let it set for a few minutes. Use the rinse setting on the car wash high pressure washer. Spray that mother down until NO Gunk residue is left. You won't get the heavy, caked on grease off of anything unless you scrape it, but you will get rid of the oil that may be on the engine, tranny etc.
That takes care of any oil you may have spilled while changing it...because it will stink until it burns off...which could take a while.
Drive home. Get a pan, unscrew the oil plug. Remove old filter. Get all that oil out that you can.
Rub a liberal amount of new oil on the rubber oil filter gasket and a little on the threads. Put on a good quality oil filter, such as a Napa Gold or a K&N oil filter. Wipe off any oil that you spilled while taking off old filter. Make certain you do not cross thread or over-tighten the new oil filter. Make sure you don't cross thread or over-tighten the oil drain plug. Put in 2 quarts of Lucas and 4 quarts of Quaker State 10 W 40. NO SYNTHETICS. Lucas oil is thicker than cold honey, so be patient.
Start it and let it idle for 5 or 10 minutes. Watch for smoke. You might see some white smoke...which is okay because we're running a little extra oil. If you have immense amounts of smoke, don't panic. After the engine is hot, take her for a spin...at least a 20 mile round trip, preferrably highway. This gives the Lucas oil time to blend with the Quaker State and kinda break in and coat everything.
If after the drive you still see lot's of smoke...we'll need to look into other areas...like leaking valve cover gaskets or bad piston rings. But, unless you've fried your piston rings...which I doubt you have...this process will please you. You'll also get some better gas mileage and a cooler running engine. Lucas products are EXCELLENT.
The whole thing will cost you about $50 or less. This is a very inexpensive way to both improve your oil system quality and eliminate possible problems. It worked for me! Good luck.
