No, blue smoke is a sign of oil burning in the cylinders. Maybe the piston rings are too worn.

I'm looking to purchase a used car. I've been doing online research and saw this webpage http://www.usedcarsmells.com . They talk about exhaust color and smells. Is it true that you could tell a lot about...


Yes this is correct, you can get important information from the colour of smoke from the exhaust:

Blue/Gray Smoke: Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber. These are possible symptoms and causes:
Valve Seals: Leaking valve seals will cause blue/gray smoke at startup because oil leaks past the seals into the cylinder after the engine shuts down.
Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder.
Piston Rings: Worn or damaged piston rings will cause blow-by resulting in blue/gray smoke.
Worn Cylinder Walls: Worn cylinder walls cause blow-by resulting in blue/gray smoke.
PCV System: A stuck closed PCV valve will cause excessive crankcase pressure resulting in blue/gray smoke.
Black Smoke: Black exhaust smoke is an indication of a rich fuel condition. These are possible causes:
Fuel Injectors: A leaking or dripping fuel injector will cause a rich fuel condition.
Fuel Pressure Regulator: A stuck closed fuel pressure regulator will cause a rich fuel condition.
Fuel Return: A restricted fuel return line will cause a rich fuel condition.
White/Gray Smoke: White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes:
Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber.
Engine Block: A crack in the deck of an engine block near the coolant jacket will cause coolant to enter the combustion chamber.
Head Gasket: A damaged or blown head gasket will cause coolant to enter the combustion chamber resulting in white/gray smoke coming from the tailpipe.

Why is it that my multicab sometimes emits white smoke and gone after a minute and with burned engine oil smell?


Blue smoke is oil,white smoke steam or trans mission fluid. Check that auto fluid not going up a vacuum line if it has a modulator.

Occasional heavy smoke on tickover, but not using oil and oil clean.


HI do you now the color of the smoke
if engine emits white smoke its not burning the fuel
it could be water mixing with fuel = head gasket even tho you
dot have water in the oil
if engine emits black smoke - that's excessive fuel to air ration
check air filter & air inlet to see if clogged

if engine emits blue smoke - excessive oil consumption
cloud be valve seals

Car smoke real bad when you crank it up


Sounds like you could have a leaking fuel injector or a bad fuel pressure regulator causing a rich condition at start up or possibly bad valve guide seals causing oil to leak into the combustion chamber, is the smoke blue or black when you start the engine up???

I've changed the oxygen sensor and the O2 sensor and new plugs on my 97 dondge 3.9 van and it still blowen black smoke (rich) seems to run real good on top end but theres is a flat spot where theres no...


Black smoke indicates no air, check your air filter, if you have done that and it is ok, check the PCV valve. Thats about all that I can suggest. Hope that helps.

Blue smoke go out my car in the morning when engine begin to work


Normally it is the valve seals. They allow oil to leak from the valve cover area to the cylinder. When the car is started it will burn off the oil and cause the smoke. There are other issues that could cause this.

Puffs blue smoke


Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.

This could mean a cracked head or bad gasket....It costly
