02 Altima 2.5 4 cylinder. There is oil in my 3rd and 4th spark plug well. The engine will not turn over. When it was running it burned oil very quickly, about a quart per week. The oil smells like gas. Is there anything I can do to fix this and get it running again?

Oil in the spark plug tube wells will require replacing the valve cover gaskets and plug tube seals. Have someone familiar with Nissans check out this car.I have seen this engine initiallly have bad cat converter, the cat starts to break up and gets drawn into the engine destroying the bore, pistons and piston rings. Check the basics first, check the condition of the spark plugs ensure they are not "mechanically damaged" or oil fouled, and check compression and cylinder leak down test.
HOW DOES THE CONVERTOR ENTER THE ENGINE CRANKCASE? i have not seen many bad kats yet hear abot them often?
Reversion waves when you let off the gas suck converter debris back into the engine through the exhaust valves. The fine particles end up scraping the cylinder walls and cause all sorts of damage. It happens because the converter is so close to the motor and the reason they do that is so that it warms up and lights off quicker to reduce emissions. Converters need heat to work.
Check basics_ compression spark and fuel. Last car i saw with plug wells full of oil had a seal behind oil pump slinging the stuff like jedd clampit had just shot it.
Sounds like it is time for a serious gasket job. If you want it, it sounds like head gasket and valve gaskets are needed. Was there oil on the ground below the vechicle as well?
PUT SOME OIL RINGS ON YOUR PISTON OR BUY SOME OIL FOULERS FOR YOUR NEW PLUGS AND ALSO CHECK AND SEE IF VALVE GUIDES ARE NOT DRIED UP OR BROKEN
From the sound of it you need to get a valve cover gasket set make sure it includes the spark plug tube seals,cause thats probably where it is leaking
