If it's actually white then it's water. Probably a blown head gasket. If it's got a slight blueish tint to it then it would be oil. If it's oil it will have a strong burned oil smell to it.
the smoke that comes out of a exhaust pipe is supposed to be white
You may have oil on the exhaust, once this has burnt off the smoke should stop.
I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.
i have 05 e55amg and just notice white smoke from the exhaust when i start the car and i will drop it off to the dealer to check what the hell is wrong and i will update as soon as i find out.
Water vapour due to condensation in the exhaust pipe.
You should stop immediately.
White smoke from the exhaust pipe is a sign of coolant entering the combustion chamber. Commonly caused by a blown head gasket. STOP driving this vehicle until you have this repaired or you will destroy this engine.
Maybe a blown head gasket
the "smoke" is always there when you breathe in the morning, when its cold, you see like a mist, that what that is, its just you usually cant see it
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
All cars blow white smoke when they are cold especially on a cold morning .Worst case scenario if it blows excessive white smoke all the time is a blown head gasket
thick white smoke generally indicates coolant leaking into combustion chamber . check for faulty head gasket od cracked head
