Your engine burns some oil. It's one of most often problem with Camry engine, usually replacement of valve seals solve it.
If you do not notice change in the oil level, do not worry many people have it even on new cars.
oil burning . Condensation.

A bad fuel injector can cause your 2004 Toyota Camry to smoke when you start it up. A plugged air filter can also cause it to smoke.
because its broken.
The valve seals most likely.
Black smoke is caused by excessive fuel in the engine
smoke coming from the a/c why is this?
White smoke from the exhaust indicates that your car is burning water in the combustion chamber. This is an indication of a bad head gasket.
heater core
i had one. put it in the exhaust pipe. when the smoke starts coming with the engine ON it is good news. if it smokes WITHOUT the engine being on, you have proberly got a leaf or something catching fire. at this stage, run!!!
Anything's possible, I guess...put Cruz Pedregon in the Camry and your grandma in the Viper, and the Camry will probably smoke the Viper. But given roughly equal drivers? If you're driving a Camry, don't race Vipers for pinks.
black smoke means your burning oil and the head gasket will go sometime soon
