Typically a leak. Either you're leaking oil onto the exhaust manifold or possibly coolant. The exhaust manifold gets very hot and any oil that drips or flows to the exhaust manifold will boil off and produce smoke, much like an overheated frypan with grease in it. Note that it is possible that the oil can catch fire and cause some serious damage to the engine. You should take care of the leak as soon as possible. Alternatively, you could just go to the manual car wash and use the high pressure system to clean the engine compartment and get all of that oil out of there. It COULD be blowby, but that would need to be some pretty serious blowby.
Probably a coolant leak.
Yes It should all burn off eventualy.
could be steam from a leak caused by the accident in the coolant system or smoke from a transmission cooler leak they are both up in the front of the car.

Oil leak? Valve cover gasket? Power steering pump?
oil filter oil leaking on to exhuast pipe and burning
Not likely. Smoke from under the hood denotes a leak. Either your coolant or oil is leaking. White, thick smoke is oil. Could just be a gasket. Thinner hazy smoke is coolant. Check your hoses. Look for fluids/wet spots. Bad plugs can missfire, and make your exhaust smoke.

White or gray smoke coming out from under the hood of a car could be the result of a small water leak spraying water on a hot engine. A running engine is naturally hot enough to create steam when water hits it.
