White smoke on startup

What causes white smoke and engine blow by? What could make a diesel engine produce white smoke? What engine treatment to stop car smoke? One reason for white smoke is very common and completely harmless.

White smoke can be a big problem or not, depending on the thickness. The white smoke is the result of normal condensation which builds up inside the exhaust system. Diesel engines need high compression and heat for fuel combustion. It can be especially difficult to start a diesel engine during cold weather.

Diesels with an engine temperature below about F. Moved to golf cart community and for last year averaged 175. I now drive highway and city. Car in garage when not in use. One way is oil this is normally a whitish blue to blue smoke and has the apparent smell of oil being burned. Next could be antifreeze when it is being burned it has a sweet type of smell and tends to dissipate in the air rather quickly.

When I start my car for the first time every day, I have white smoke come out my exhaust usually for about a minute or two but it runs fine after that. On cold winter days, it is common to see white smoke from exhaust pipe as soon as you start the car. As the engine warms up after a few minutes, this white smoke will not be reduced because condensation is dissipated.

This is nothing but steam caused due to condensation. The reason why there is white smoke on start up will depend on the condition of the engine when the white smoke is notice. If you notice the white smoke from exhaust only when the engine is very col then this condition is normal this happens because the condensation is steaming off when you start the engine. Then everything is fine as usual.

It never used to happen. But it is always a good idea to keep an eye on your oil and coolant levels on any car, smoke or no smoke. Even in a hot and humid climate, there will be some condensation in the exhaust system overnight.

In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time. Some white smoke is normal on cold start -ups. Excessive white smoke could be an indication of inoperative glow plugs, loose injectors, low compression from worn rings or bent connecting rods, or coolant leak into the cylinders. So why is white smoke still a problem? Temperature, plain and simple.

Of all the possible causes an from my experience, the lack of temperature at which the fuel is burning within the engine is the single biggest cause of white smoke. So to me, the simple solution is to increase the temperature at start up. If just at start up this could indicate moisture in the exhaust, this can happen when the engine is turned off and moisture forms in the exhaust through condensation from the air. Lasts about mins pretty rough runninh until warmed up then seems to run great.

If so how long do nbn I have generally before i NEED to get that fixed. Can mean accumulation condensation in the exhaust. Just whispers, of smoke , is nothing to be concern about. If white smoke continues to come out the exhaus, while running.

Leaking coolant is being burnt. Someone must be pretty new to automobiles for not checking it first. Glad you got her fixed. Smoke at Startup then Dissapears was created by ironheader When I start up I get White Smoke then once i drive it and get the temperature up it disappears.

But when i turn it off and turn it back on 5mins later I get the white smoke again, but once it gets a bit hotter it disappears. Its not a BHG, i already had it tested for that, and im not low on coolant. But excessive white smoke likely means coolant is leaking into the engine combustion chambers.

Condensation can turn to vapor, providing what looks like white exhaust. A little white smoke that is odorless coming out of a COLD four stroke engine is likely to be steam from condensation in the exhaust system, and it won’t last longer than it takes the pipes to warm up.
