Smoke can be from rings worn out, cracked piston, valve guide seals if smokes at start up then stops, fueling issues if fuel is to rich but that smoke is usually black, also if head gasket is blown or head is cracked water burning turns into steam which looks like white smoke. This can also be why won't start just turns over.

Smoke smells when ac on nissan sentra


The speed control of your fan has resisters that are in the venting system to blow air on them to keep them cool. If they overheat and or burn you will lose your low and medium speeds of the fan. If you run the fan at full see if the smell goes away. Your engine could be burning oil on the outside of the engine block, make sure that the weatherstrip where your hood meets the fresh air intake grill is sealing tight.

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...

sounds like blown head gasket or cracked head or block letting coolant into the oil pan, check your oil to see if it's thick and light colored.

Overfilled engine oil on a 2003 porsche 911 turbo.now smoke comes out of exhaust--HEAVY Smoke.I drained engine oil again(along with the turbo)put in 9.25 qts of oil,still having heavy smoke.


The oil was overfilled this could cause a large amount of oil to enter the exaust and possibly the intake depending on crank case ventilation conditions. If you are positive engine oil levels are adjusted perfectly(warm engine check level running for dry sump oil level ect.). Time is needed to burn off oil residue in exhaust system and intake. Warm up engine low rpm no load, drive vehicle slow with little boost over 5 mins slowly raise rpms for another 5 mins keep driving smoke will burn off while making other drivers mad. sorry just smile and wave.
The engine oil on this vehicle should only be changed by an experinced tech.

97 kia sephia smokes when first starts, smells like exhaust smoke


Black smoke is fuel.
Blue is oil.
White is coolant / water.

Fuel is caused by timing and cold start system and requires some discussion to clarify.

Oil burning only on start is caused by failing rings on your cylinders. Oil then enters the combustion chambers and burns when you start the engine. If it continues to burn when running in particular when you accelerate it will also indicate ring/cylinder failure. It can also be from a failing head gasket where oil travels from the lubrication system into the combustion chamber. Some of the anti smoke additives available at the auto supply store do help.

I doubt you are seeing white as you say is smells like exhaust. White is coolant in the combustion chamber or exhaust system.


Hope this helps you.

2004 Jeep Liberty it pasing oil an prestone that just apend onse


is it leaking, or burning in the combustion chamber? Comming out the tail pipe? Blue smoke is oil, white smoke is water, black smoke is carbon. Smell your exaust; smell like "prestone"? Does the engine over heat? My guess would be a bad head gasket. Is the oil a light brown color?

If the smoke is blue it is burning oil. If this is a 3.0 liter engine this is common as the valve guides have dropped which allows oil to draw down the valves stems into the cylinders. If your smelling raw gasoline park it as it may be a fuel leak. If the smike is white your burning antifreeze; this may even have a sweet odor to it. If this is the case you have big engine troubles, bad head hasket, cracked head or ???
I hope this may have helped,
