You need to get a better idea of what the smoke is. Is it petrol or diesel? Does the smoke linger or disappear quickly? If it is a small amount that disappears quickly it isn't likely to be a big issue.
If there is a lot of smoke get someone else to help as you reverse it out and try and see what colour the actual smoke is. The colour will give a better clue as to the problem. It could be slightly coloured as blue, black, grey or white. See the attached image for what they could mean.
If the smoke is white you have water entering the cylinder because the head gasket has failed and it will have to be replaced - a big job , only a repair shop can do it. If the smoke is blue you have excess oil getting in the cylinder because one of the valve seals or an sealing piston ring have failed - replacing them is even more complicated than the first fault. If the smoke is black then the air fuel mixture is too rich - too much fuel. This is caused by a faulty injection, it will have to be diagnosed professionally with testers to find out what is wrong. A visit to a repair shop is mandatory.
Sometimes diesel engines will put out black smoke under extreme acceleration. Other than that, they shouldn't smoke. Black is excess fuel, White smoke is water and bluish is oil. White smoke on a cool morning is not necessarily a sign of a problem unless it happens every time you start it through a warm day. Hope this helps.
If its a petrol motor then they will blow a little white smoke/steam on startup until the exhaust heats up. The engines computer knows that its cold so richens the petrol/air mixture to warm it up faster . You should let it warm a little before driving off or if you can't then don't rev it hard til it starts to warm up. All the parts inside the engine need to get to optimal running temp to wear properly. Most engines wear more on startup then when they have been running for a long time. In regards to smoke blue is bad (oil) black is bad ( to much fuel) and white is usually on startup.
