Camry smoke on startup

Check trans. fluid level while engine is hot and running, Check it twice to be sure that the level is full. The white smoke could be something all together different like a blown head gasket. check to see if water is mixing with the iol by looking at the oil fill cap, if you see bubbles and a whitish milky looking color under the cap.

nothing to worry about, valve seals leaking alittle, when you shut it down a little oil leaks into the cyclinders, when you start it up again the oil is buring off the pistons,,,,hope this explains your trouble???

I think the overfilling indeed is causing some oil burning on startup when clearances are wider. Drain it down to the right level, by taking out the sump plug for a second or 2. You can do that with the engine cold, but use a dead clean catch container in case some oil has to go back in.

If that smoke is white then it's probably nothing more than the water from  the combustion gases that has condensed on the exhaust line, nothing to worry.

If there is no loss of Coolant, which is a sign of Head gasket failure to the combustion area, which generates white smoke, I would recommend after 4000 miles of your mileage alone, a complete Service of Engine Oil and filter, AIR filter and Fuel filter.
An inexpensive way to find a recurring combustion problem, At 60k miles, the Spark plugs should still be good, but pull them anyway, just to confirm.

This is probably oil burning off which has seeped by the valves and rings overnight. Sign of a higher-mileage engine. An oil additive for high-mileage engines may help.

Otherwise, it's not a serious problem, just fair wear and tear.

This problem is common but often over looked. Moisture vapor is a grayish white color but it dissipates very quickly. Smoke that is grayish white is caused specifically from burning oil. The problem you have is a small seal called a valve seal. It is very common in cars that sit a fair amount of the time. The seal gradually starts to leak and allow tiny drops of oil to drip into the combustion chamber. When the engine is started then it smokes until the oil is burned. Due to the amount of time that your car smokes after start tells me that the leak is very small. That is why there is no oil consumption. This is not going to harm the car unless it becomes very bad and then the only thing that would happen is more smoke and fouled plugs. You can start using a heavier weight oil and add an oil treatment to the oil when you have it changed. This may evin stop it all together. Hope this answered your question. Please rate this solution if you think it has helped. Good luck and thanks cj2176.

The black smoke is not a problem, it just means that there is a rich gas mixture in the motor to start the car from cold.

This is normal with a cold engine...

Sometimes there is a seeping of oil from old rocker cover gaskets.

If the oil is not running out in a trickle. Don't worry about it...

Wipe the oil away with a rag and see if it comes back soon.

Check the oil level on the dipstick regularly and you should not have any trouble...

Smoking & sludge ...OK, first, smoking on startup generally is the result of worn valve guides or valve stem seals. Excessive sludge in the engine can worsen this condition as sludge buildup can block oil from draining back to the pan, instead remaining inside the valve cover where it can run down the valve guides overnight.
If you just got the car and want to get rid of some sludge, change your oil every 2000 miles for a few months. Use a good quality oil and add a pint of marvel oil to it each time. On an engine with substantial sludge, I don't advise using any flush products. They work too fast and end up jamming residue into the oil screen, preventing proper oil flow to the pump. It took a long time for the sludge to form, don;t expect anything will remove it immediately short of a complete teardown & rebuild. If that's the only problem you have just follow what I said and you will be OK.
No coolant loss, overheat or anything? Did sludge suddenly appear or as I thought, it just built up over time?
