Question about 2001 Toyota Corolla
Burning oil every 1000 miles no leaks
If you are sure it has no leaks, the only other possibilities are worn oil rings or valve stem seals. Generally if the oil rings are worn then the compression rings are as well, so get a compression test. If readings are down on spec, which is about 150 psi., add a tablespoon of engine oil to each cylinder in turn through the plug hole. If readings rise, then it is worn rings at fault. If not, then suspect the valve stem seals.
On these engines though, there are several characteristic oil leaks which may be hard to spot, being the cam cover gasket, crank nose seal, and the distributor o-ring seal.

I see you have a four cylinder since it only holds 4.5 quarts.
2006 manual confirms your oil consumption is within allowances. Just check oil every time you buy gas like the manual reccomends. Do not over rev engine or accelerate from stops at max capacity of car as these can increase oil consumption.

Well looking at the age of your car,it would need a valve seals replacement,in order to fix your problem.This would cost you around for about 1500-2000 $.

If you see no signs of burning oil ie blue smoke from exhaust, ticking from the engine, then most likely you have a valve cover gasket leak. The reason you wouldn't see the oil in the driveway is the oil is burning off on the exhaust manifold. Check around the valve cover gasket for seepage (usually around the bolts).
