Your rings are gone.......when the engine sits oil slips through the rings into the combustion chamber, and when you start the white smoke you see is the oil burning off. this looks ugly, but is not detrimental to your car. Make sure to keep the checking the oil, as you are burning some off each time you start. 
some engine treatments claim to be able to fix the problem by just adding a supplement into the oil. Z-max ect....or Lucas. 
these lube up the old rings and help to stop oil from slipping past into the combustion chamber. 
the only way to totally fix it is to do a rebuild, and get new rings.
I hope this helps,

Hi, sounds like you need to replace your valve seals or if yours is the turbo the sealing rings in the turbo are worn.
What happens is that oil over night or when the engine is stopped runs into the intake of the engine in small amounts then when the engine is started the oil is burnt hence white smoke.
Check each spark plug in each cyclinder to see is one of them or all of them charred with black burnt oil deposits.
In one plug has more than the rest you can be rest asured it is the valve seals.
If it is the turbo version it has to be the turbo sealing rings.
Best to replace the turbo in this case as it is only a mater of time before it goes. this as we always say is the warning light on it telling us that its days are numbered.

No disrespect to other replies, but Blue smoke usually means oil, black smoke means fuel, and white smoke means (potentially) coolant.
Check your head gasket, and your coolant level. if you are constantly topping up the ol' prestone, you might want to have a better look around.

White smoke coming from exhaust,need help


White smoke is condensation from a buildup of water from within the exhaust system - if it was blue smoke then it is burning oil ... let car sit for a few minutes and take the dipstick out - wipe it clean - then re-insert dipstick - take it back out and check level against gauge at bottom of dipstick if you think you may have overfilled the oil

White smoke on start up


white smoke is a sign of water in the exhaust , the question is how is it getting there , if only when initial start then goes off then it's only condensation in the exhaust system heating up and turning to steam , if it goes on when driving check coolant level and check engine oil for signs of coolant contamination

I changed the turbo now white smoke coming out of my exhaust


This seems to be a symptom of a blown head gasket.
White exhaust smoke is an indication of water / coolant in the exhaust. The car running sluggish and using lots of fuel can be caused by compression loss.

Look at the coolant level color and smell (with cold engine - don't open the high pressure reservoir with engine hot as hot coolant may spray you in the face). If you have a blown gasket, the coolant color may become brownish and it may smell bad or the level will get lower even if you have just refilled the cooling system.

What you can also check for is bubbles in the reservoir. With engine cold, remove the reservoir cap. Start the engine. Try to rev the engine (or have someone do it) and observe if there are bubbles in the reservoir tank. If you see lots of bubbles, you have a blown gasket.

White smoke came from the exhaust pipe and the car killed in motion. I check all fluid levels were fine, once i started the care again and proceeded the accleration was a bit rough. After a few minute


white smoke mostly is caused by over fueling so what i suggest you do is first of all check if there is no leak on the injectors and if there is none which means your valve sterm seals are damaged.When the head gasket is blown out you may have problems like :-loosing power when driving,over heating,idling problems and oil mixing with water, its not your head gasket.

White smoke coming from exhaust when i start car


My friend, you have a good vehicle. Sediment, fuel and other fluids build up as vehicles sit. Idling your vehicle for a few minutes before driving is a smart idea. Unless it is black smoke( header oil leak) you should be okay. Just keep track of your fluid levels

White smoke, at the first start of the engine and


Does it use any oil, or lose any coolant? If not, do you make a lot of short trips, then shut it off by chance? If your not using oil, or coolant, then I'd say take it on a long drive at highway speeds to drive out the moisture laying in your exhaust system. Recently had a muffler go on wife's car that does a lot of short trips, and old muffler was almost full of water from condensation and obviously poor exhaust design, that allowed it to build up like that. Took it next night on trip about an hour away. Every time I took off, or passed a car, white smoke rolled out the back. On way home, it stopped and cleared up.

Hi:
My first thoughts are that you have a head gasket or intake manifold gasket failure. This is why you have the white smoke. If you run it too long, your catalytic converter will be destroyed. Check for coolant in your oil too.

I have a lot of white oily smelling smoke come from the exhaust when I start it after driving over 30 miles at one time. Doesn't do it if I just drive around town. Held a cloth over exhaust and no residue...


I concur with emissionswiz; it sounds like a typical sign of a leaking of 'blown' head gasket and the white smoke could well be coolant+water.
