Everytime the car is cold or parked for over 2 hours then u go to turn it on it releases alot of smoke. After the car is turned on it doesnt do it anymore. It's very clear white smoke. Why does it do that and is it bad?

sure its not water vapor...as a car warmes the heat drives the water out of the oil...its normal...if its smoke thats another matter.look in oil and water/coolant for sludge....

White smoke is too much fuel. Black smoke would mean it is burning oil. Is the car difficult to start when it sits a long time? I would say that you have a valve letting fuel seep into your cylinder causing your car to flood and create the white smoke.

Pure white smoke is usually a sign of burning coolant. If it has a little bit of a blue tint to it, it could likely be worn valve seals. Rich fuel conditions will produce black smoke. It could be nothing more than a little water vapor from condensation in the exhaust.

I agree with Mclaren about the cause of the smoke conditions. More than likely it is harmless water vapor. But as suggested do make sure to check for a milky substance in you oil, which would be collant getting in to the oil pan. Now you may with the engine cool find some on the top of the dipstick. If the humidity is very high in your area this can happen. So you may at times find it on the upper part of the dipstick and not in the oil that is the oil still looks normal in color which should be somewhere between clear brown (new oil) to black color (old oil). If you see a creamy brown like coffee with cream in it, you then have a major problem on your hands. If as McLaren said you have a slight blue tint in the smoke that could be the valve guide seals are leaking. This is annoying but will not neccasarly hurt the vehicle. As the oil burns it will produce smoke for a few minutes.

valve seals could be bad. also if the smoke goes away when the car warms up it's the valve lash. the valves need adjusting that's all.

black means rich (too much fuel) white ushually means oil and if its a blueish tint its burning anti freeze.
