Sounds like coolant is leaking into the engine. Which means it probably has a cracked or blown head gasket.
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
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.
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.
