A2V asked:
When there is blue smoke from your exhaust what does it mean? Well, blue smoke means that the engine is burning oil.
Now, there are two causes why a blue smoke comes out the exhaust. The first one is that the engine might have a bad ring this is the most common problem. When the engine had a bad ring the effect is not just a blue smoke but also low power especially when your car is going uphill. When the blue smoke is accompanied with a loss of engine power especially when driving uphill, then there is no other cause but a bad ring. The ring prevents the engine oil from entering the engine cylinder and also maintains engine compression to generate power, if the ring is bad the piston and the cylinder will not be fully sealed and the oil will start entering the combustion chamber, this oil will get burn inside the combustion chamber and a blue smoke will comes out the exhaust. Also, a bad ring causes weak compression, if the engine has weak compression you will notice a weak engine power.
Second is when there is a blue smoke from exhaust when accelerating your car. In this condition the cause is a bad valve stem seals. When the valve stem seals are bad the oil is leaking past the valve stems going into the combustion chamber. The oil inside the chamber will get burn thus a blue smoke will comes out the exhaust.
There is another reason of blue smoke that comes out the exhaust, however this is only applicable when your car has turbo charger. Turbo charger have seals that gone bad, in this case the seals of the turbo charger leak and causes the oil to reach the exhaust system, the oil will then smoke when it get contact with the exhaust system component that is hot. The smoke that produce will comes out the exhaust, this the blue smoke that you see from the tail pipe.
