Not at all uncommon. New heaters have to glaze over the file tile in the burner chamber and will often smoke and smell during the first week or so of operation.

Using a mirror, check to see that your flames are about 4" proud of the burner tubes when running. As long as they are and the color is a nice blue with little to no yellow/orange color, the heater is fine.

White smoke from BMW 740i exhaust


white were? the exhaust tip, or other spot, long pipe, name spot?
white, is steam or OIL.
oil smells like burnt oil and takes for ever to dispate
steam is water, and smells , sweet due to 50% glycol inside.
and goes away fast.
but all Gas engines make water at all the time running as a by product of combustion and for sure on cold days, some times full time cold
due to climate effects.
does your neighbors car smoke at same time, (look)
bingo , dew point.

all gas engine smoke cold started, (steam)

so first find out what it is,
take the dip stick out of a hot engine. stalled, drip it on the exhaust
see that smoke ,smell it? that is burning oil
now you know what you have, steam or oil. smoke.

My harley smokes


all engines do cold. its water vapor and or the hot exhaust, causing the air, to change dew point, (looks like steam)
on the white smoke smells like burned oil , it is, and is slow to dissipate like steam, (see moms tea pot , and steam fast dissipation?)

if it is oil , its most likely bad valve guides and seals, or both.
if a compression leak down test passes, its not rings, (mostly)

Burning smell when running car ? Oil or electrical ?


open the hood and observe the smoke(if any) electrical smell will show a yellowish color with a blue/green/red yellow flame and it moves fast..oil smoke and antifreeze smoke(vapor really) will sort of "steam" off from near the area its leaking from when hot.. brake smell and clutch smell are almost the same since both use like materials for friction..keep an eye on this for potential problems and may need to move the vehicle outside so if it goes up in flame the house wont/grarage whatever//

There is white smoke coming out the tailpipe no smell of antifreeze


If it doesn't smell like sweet then you most likely got a bad tank of gas. Just to be safe keep an eye on your engine temp. and coolant levels.

Smoke coming through air vents


Is it smoke? Or is it steam? If it's really smoke, it will smell like burning wires and you have an electrical short somewhere. You're going to have a fire unless it's fixed.
My guess is that it's probably not smoke or you would have already had a fire.
With that said I'm going to say that it's steam in which case your heater core (which is a small radiator located under the dash) is leaking coolant and the resulting steam is rising through the vents. The steam will have a sort of sweet and yes, a steamy smell to it. It will also leave a funny film from the radiator coolant coating the inside of the windshield.
The heater core should be replaced if my assumptions are correct.

White smoke, water vapor at initial start-up. drives a few miles, smokes again. could it be a vacuum regulator? 2001 jaguar s-type


Water vapor coming out of the exhaust at initial start-up is normal; that is condensation that collects when the engine is not running. White smoke at start-up depends on a couple of things. Tell me, where do you live? When the weather is very cold, all engines will emit steam (white smoke) when they are first running; this stops after the engine has been running a while and is warm.

In short, if this is only happening at first start of the morning and goes away over time, there is nothing wrong.

If, however, the "white smoke" continues and never stops, you may have a blown head gasket.

Temp gauge reaches red line and smoke/steam from under hood, but no leaks of any kind. This after recent oil change and thermostat install.


Something is wrong. What does the steam smell like? Oil or antifreeze?
Look closely for coolant seeping onto something hot and vaporizing, if that's what you smell.
Check your coolant level and oil to verify if you may have a leak.
