Its kinda cold out about 40 and my truck has been smoking none stop all night out of the exhaust.

its not blue but a greyish color i know its common for cars to smoke in this type of weather but i thought it cleared up after awhile.

Is this a problem?

 

Gray smoke when the engine is warmed up.

Usually appears when the engine is accelerated and may be especially notable when the engine is idling. This is unburned oil drawn into the combustion chamber past worn rings or valve guides. In the best case, the oil is just too thin (old oil, wrong weight) and is slipping past the piston rings and valve seals. The oil sump may be overfull. The cure is a simple oil change. But that won't solve gray smoke resulting from a worn engine. In the worst case, gray smoke means the engine needs replacement or serious internal repair.

Are you sure it's Gray ?

 

Steady white smoke; warm engine; any air temperature.

This is bad news. The engine's coolant is leaking into the combustion chamber and creating a steady flow of steam. Caused by a leaking head gasket or a crack in a cylinder head, most commonly in the exhaust port area. Usually requires serious surgery on the engine.


Some mufflers collect water and hold it for a time. Drill an 1/8 hole in the bottom to drain. Install a sheet metal screw in the hole after draining.

 

you shouldnt smoke its bad forou lol


dont beat me up i smoke when i drink its a joke

 

wow look at my spelling seems im ready for a smoke

 

Are you getting "smoke" or "steam"? Steam dissipates quickly whereas smoke will linger and creates a haze that is visible. If you smell your exhaust you can tell quickly what is happening, if the "smoke" has little or no odor then it is the water vapor comming from the catalyst, if it smells sweet like hot chocolate then you have coolant getting into cylinder(s) ie head gasket issues, and if it smells like hot or burning oil then you may have piston ring or valve seal issues.

 

It smells sweet..kinda smells good really ,my coolent level has been ok..

if its grey will it be a dark grey?

if not its a white then.

it shouldent be smoking constantly in cold weather correct?
ive noticed it kinda in the past but dident pay attention to it

noticed last night and ran my car for a hour in the driveway after getting back from the store and when i came back out it was still smoking, i do not get any type of haze on the paint of the truck, and it dissipates fast.

im taking a trip to texas in this truck should i get it checked out before i go?

*edit*
Ohh would a bottle of LUCAS fuel injector cleaner do it as well??? i know seafoam smokes the truck. but i swear it was smoking before.

 

Could be that your area has switched to the 'oxygenated' fuel already? Could be the humidity is high?

Idling for an hour will in most cases cause MORE 'smoke' because the exhaust system does not get up to it's full temp and MORE condensation is being generated and that's what you are seeing out the pipe...

If you still have the stock muffler, it should already have a 'weep' hole in it, but if you do happen to have an aftermarket one, depending on how 'deep' it is, you could have a collection of condensation in the bottom of it... A good, long hwy run for about an hour or so should dry it out....

I've seen cops that are parked in the median yaking at each other or buzzing you with their radar guns and they all seem to have 'steam' coming out of their exhaust... They idle those cars all day long and run 'em hard other times, but it's the idling that'll generate the steam the most IMO....

Don't start dumping stuff in the tank to try to 'clear' it up either.... I think you just need to go out and drive your truck and 'blow out' the carbon, so to speak..
