Get it inspected, you may have a blown head gasket. If you do not get it looked at and it is a head gasket issue you could destroy the 02 sensor and the catalytic converter.

Blue smoke after being driven for awhile


if you can then smell the smoke. if it smells of petrol you will need a tune on your car ( getting too much petrol ). if it has no smell or very faint then it could be your head gasket. (water getting to the head causing steam ) worst case would be piston rings expanding through heat and letting oil through ( smell of oil burning ) check oil filler cap and dip stick for white gunk/check exhaust for water dripping out. these are head gasket signs

Thick white smoke that smells like burned rubber comes out the rear of the car continuously, but functions normal.....


could be oil that has built up in the exhaust, check the engine oil and see if its up to the correct level top up if required and keep a check on it, it may also be useing to much fuel if its diesel as excess fuel burnt shows up as white smoke

Engine concern


Smoke (blue or black) or steam (white)? White smoke is really steam that is caused by water leaking onto hot surface. Could be leaking from hose running to heater coil under dash, or something else. Check radiator water level to make sure water level is ok. Blue smoke is oil burning. This could be dangerous, caused by similar scenario of oil leaking on a hot surface (from a gasket leak, etc), or exhaust fumes. Black smoke means something is actually burning and could indicate fire. Black or blue some could fill vehicle cabin with toxic fumes, even if you don't smell anything bad.

WHITE SMOKE OUT OF EHAUST


White smoke is caused by engine coolant / antifreeze being processed in the combustion chamber(s) of the engine

Keep in mind that, on a cold day you may see what appears to be white smoke from the exhaust that will disappear after the vehicles engine has warmed up to it's normal operating temp.. This is a normal reaction called condensation... condensation is the result of a small amount of water/dew being drawn into the exhaust usually collecting in the muffler and/or the catalytic converter.

Hope helps.
