My understanding of exhaust smoke is that Blue is oil, Black is unburnt fuel, White is unburnt diesel on cold start. The main question would be, how much smoke and when does it do it?
Blue exhaust smoke is burning oil.
what kind of gasoline are you running? and what color is the smoke?
I know the white smoke would be caused by coolant, which would be leaking into the combustion chamber.
The exhaust should be colorless. Smoke is created by an imbalance of the oil:fuel mixture. Black smoke is too much fuel (rich). White-blue smoke would be too much oil.
If you nicked the oil pan it could cause it to smoke from engine area. Is the smoke coming from the exhaust or engine bay? If exhaust, then I highly doubt it was caused by the curb incident.
I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.
Bad exhaust valve / Not seating in the head
engine burning oil( white or blueish exhaust smoke ), water in oil, oil in water, water in exhaust.
Why is smoke coming out of my 96 s10 oil fill and exaust blowing grey smoke
yes, and also usually there will be white smoke in the exhaust.
White "smoke" in the exhaust usually means there is moisture in the exhaust stream.If the "smoke" appears while you're driving away shortly after the car is first started on a cold morning it is likely the condensation boiling off the inside of the exhaust pipes (steam). This is normal and goes away as the exhaust warms up. The condensation is also normal; it usually happens after the car is shut off on a cold day and the water vapor in the exhaust gases is allowed to condense as the exhaust system cools down.If you have white smoke all the time, you may be leaking coolant into the cylinders which could mean a head gasket leak. Usually there is oil residue in the exhaust as well, which would be a tell tale sign of a blown head gasket. Then the white smoke would have a hazy blueish tinge to it. Also, certain chemical engine cleaners and fuel additives can create a white smoke. Have a mechanic check it out if necessary.
From the front of the head it's EIIEEIIE. This is the same on both sides - (I=Intake, E=Exhaust) With the valve covers off the rocker that aligns with the exhaust port is the exhaust the other will align with the intake manifold runner this would be your intake
For steam to come out the exhaust you probably have a bad head gasket or a cracked head. If the turbo had an oil seal fail it would cause blue smoke to come out the exhaust.
It depends on what color of smoke and how it smells. The question is somewhat vague. However, if the smoke is white it is due to burning oil. Black is from burning gasoline. If the smoke is coming from the exhaust pipe then you either have leaking valves or oil is blowing past the piston rings, both are significant problems. If the smoke is coming from under the hood the most likely issue would be leaking valve covers or a leaking PCV valve. Hope this helps, if not give some specifics on the smoke and I can better help you.
It would solve the head gasket or a cracked head. Sources: My dad.
It could be timing is off. Need more info. Is it Fuel injected or Carburated? Exhaust smoke? Is it black? Black indicates alot of carbon built up. May mean the fuel is burning way to rich.
The reduction of smoke stack and exhaust fumes that cause the "green house effect" would be reduced
bad head gasket , warped or cracked head
Black smoke is overly rich fuel/air mixture. Blue smoke is oil burning. White smoke is coolant in the combustion chamber. I have never seen green smoke coming from an auto exhaust. The only thing I would suspect is that this is coolant in the combustion chamber caused by a blown head gasket. If it smells sweet and you are loosing coolant with no apparent leak, then you have a blown head gasket or cracked head.
warped valve cover. bad gasket. cracked valve cover cracked block
What's wrong is the lack of oil destroyed the engine.
Could be worn or damaged valve seals.
Many reasons; check your oil.
