Blue smoke is commonly caused by rings not creating a good seal in the cylinders. To truly fix this problem you need to replace your rings. Worn valve guides can also let oil into the combustion chamber.

For some engines, blowing blue smoke is normal on startup. The 4-cylinder "flying brick" in the BMW K1200 lets a small amount of oil drain into the combustion chambers when the bike is parked on the kick stand because it leans toward the head.

What makes a car blow blue smoke during acceleration only after stopping in traffic?

One thing that will cause it is leaky valve seals At high RPM the engine burns up the oil so rapidly there is little or no smoke but when the engine is idling at a stop light the oil builds up on the stems and valves faster than it is burned and when you take off it is blown out and burned thus smoking for a while In this case you need a valve job Bad rings may contribute to this too but usually the car will blow smoke more at higher speeds if the rings are shot

Why does your car only blow heat when moving?

the smoke comes out the rear of the car in a pipe. the smoke comes out only when the engine is on. you do not have to be moving to have smoke come out. just the fact that the engine is on creates smoke due to the byproduct of the fuel and energy.
