might be an exhaust leak at the collector or the headers... Sometimes it can also be from the valve gaskets leaking onto the headers..

If that was the case wouldn't it smoke from under hood? The bluish/white smoke comes out of the exhaust
I thought you posted under hood, my mistake... If its bluish/white smoke that is not good.. Check your dip stick put the oil in your two finger tip and tap them together if it turns milky its a blown head gasket or something worst.. Make sure your engine is not running and don't every touch the oil while HOT...

Run to the parts store and get a block tester, it will tell you if there are combustion gases present in the coolant (I.e. A blown head gasket) that's what it sounds like to me, but it could also be that you've got a cylinder about to let go, since it's not constant smoking. Could be getting blowby from a bad cylinder when you get on it hard
 
Depending on how many miles are on the engine and how it was driven I would have to say
a rebult might be in order. Or it could be a simple valve seal leak. A head gsket leak would
cause smoking no matter what the rpm and also cause the radiator to over flow due to
exhaust entering the coolant system.
