My 03 wrx suddenly started blowing smoke

My car has sometimes blown some smoke after idleing for a while. only lasts for a few seconds then clears up. there is no loss of power. have had the car checked by subaru and they don't know what it is. yesterday the car started to blow smoke when idleing but stops when driven. the longer it idles the thicker the smoke. could it be the turbo?

Are you sure it is smoke and not steam? Steam dissipates quickly, oil buring smoke is often bluish in color and tends to hang around in the air a while. Steaming could come from a bad head gasket or a cracked head. Oil buring smoke could come from leaky valve stem seals or worn oil control rings.

I have a 02 dodge 1500 4.7 when you let idle and give it a little gas it wants to smoke a little blue smoke after a few seconds it clears up what could be the problem its got a 194,000 miles on it


Hello Aaron, Bad valve seals can cause your engine to smoke after start up and clear up after a few seconds of running. Sometimes the valve seals become hard and brittle. They can break up and restrict the oil return holes in the cylinder heads, causing oil to seep into the cylinders through the valve guides.

White smoke is generally head gasket blown. Water in the exhaust.

White smoke came from the exhaust pipe and the car killed in motion. I check all fluid levels were fine, once i started the care again and proceeded the accleration was a bit rough. After a few minute


white smoke mostly is caused by over fueling so what i suggest you do is first of all check if there is no leak on the injectors and if there is none which means your valve sterm seals are damaged.When the head gasket is blown out you may have problems like :-loosing power when driving,over heating,idling problems and oil mixing with water, its not your head gasket.

My mazda 626 has a strong potent smell coming from the exhaust


You don't mention what that smell is reminiscent of?

You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?

You don't mention whether the road behaviour/performance is normal?

White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.

Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.

Burning oil smells a bit like burned eggs in the frying pan.

If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...

What causes my Hyundai Sonata to Knock on mornings first start, Knock lasts for just a few seconds. I live in the tropics, so it's not cold here. Sometimes it also smokes when idling.

Hi all, Got a 2l-t Toyota motor that started to smoke white smoke suddenly, using also oil. Where do one start looking? It smoke while idling and sometimes when I start decreasing speed. Louis


this can be serious, like a blown head gasket or cracked head. has it been overheated lately? good antifreeze used? even then you can have head problems, are you losing water? oil? check the oil and look for water in the oil, check the water and look for oil in the water, is the water abnormal looking? rusty? all these are symptons of head problems

Jetta tdi 2007 running rough on start up at times. blowing excessive amounts of smoke from exhaust at times. poor idle at times feels like running on three and a half cylinders, takes a few seconds too...


You may want to check the ignition system. The smoke could be because of unburnt fuel. You may be running on less then 4 cylinders. Check if all spark plugs are firing. You may also want to use a scanner if there are error codes found in its ECU.
