Why does my car exaust smoke white only on cold start up?
If this just started then you have either a bad pcv valve (dont know if camrys have this) or bad engine valve seals. The white smoke means oil is leaking into the cylinders after the car is parked for a while. Re: My Car Exaust Smokes White Only On Cold Start Up.
Where does the white smoke come from in a car?
The best way is to check inside your cylinders and spark plugs. If the car is combusting coolant, it will clean the cylinders. So if no of the cylinders is cleaned, but the car is still burning coolant, it must come from after the combustion chambers, like from the EGR cooler.
Why does my Camry have white smoke coming out?
It started like four days ago. If I start my car (Camry 2000 model) every morning a lot of white smoke comes out and after a while (1 – 2 minutes) gets less but still little steam like smoke, clear when the engine gets hot/heats up. Also if the engine cools after parking for hours it happens.
What causes white smoke from startup + resolve?
If the volume is enlarged or in other words worn, then the piston ring widened and the gap is getting bigger. Wear piston rings, this is also the same case when the piston rings are getting eroded then the ring will widen and the gap is also getting wider.

When does a car emit white smoke?
It is normal for the vehicle to emit white smoke when starting in the morning or during the cold season. The catalyst converts the hydrocarbon gases in the exhaust system into carbon dioxide and water.
What do white and blue smoke signals mean?
Blue Smoke Signals. While white and black smoke are related to fuel problems, blue exhaust is a sure sign that your engine is burning excessive oil. This could be caused by worn or broken piston rings, glazed or worn liners, or worn valve guides.
Why is there white smoke coming from my diesel engine?
A plume of white smoke is generally most noticeable at diesel startup, particularly when it’s cold. This is due to the fact that colder air, which is more dense than warm air, lowers temperatures in engine cylinders at the end of the compression stroke.
Why does my car have a lot of smoke?
On the other hand, thicker smoke is a pretty big issue. Thick smoke usually comes from the faulty in engine coolant, which could lead to many serious problems like damaged cylinder head, blown head gasket, cracked engine block… which might cost drivers quite a lot. In this situation, we suggest to not ignore it.
When does the car exaust smoke on motion?
No smoke on motion when the engine is warm up. It happens for 1 – 2 minutes then it will reduce to normal little steam. If possible I will post a picture of it. Re: My Car Exaust Smokes White Only On Cold Start Up.
Is the smoke coming from the exhaust condenser?
Yes, it condenses. But it is more in recent time. All of the above opinions could probably be correct but try driving your car along with someone folowing you from behind when the car is warm and the smoke/ steam has stopped and let them observe to see if there is smoke coming from your exhaust when you accelerate.
Why is my car smoking under the hood?
Older engines produce more hot spots, which make the car smoking under hood but not overheating. Worn out piston rings and clogged PCV tube or valve are the culprits that cause this smoking issue. The timeworn rings make the pistons to siphon fuel into the cylinder where it burns and creates smoke.
What causes blue smoke when starting a car?
When a car is producing blue smoke it means oil is getting into the combustion chamber for one reason or another and being burnt along with the normal gasoline. This creates a blue colored smoke which is passed down the exhaust system and then exits the car along with normal gases.
Why would a car blow white smoke?
White smoke is most prevalent in cold or frosty weather conditions. The white smoke is caused by condensing steam when you first start the car. In normal conditions, the white smoke will eventually dissipate or disappear as the engine warms up. Coolant leaks are common causes of tailpipe smoke.
What causes a car engine to smoke?
A car engine can smoke for several reasons. If the smoke is blue, it means it’s burning oil. This could be caused by valve stem seals, worn rings, a plugged PCV valve, not changing the oil for extended periods, too high of an oil level or transmission fluid being sucked into the intake manifold from a bad vacuum modulator.
