What causes blue smoke from car exhaust?

Blue smoke can often look like grey smoke at first. But if you notice a distinctive bluish tint, it may signal that the engine is burning lots of oil. This could be due to worn engine components like piston rings, valve seals, or PCV (Positive Crankcase Ventilation) valves.

Can a bad exhaust valve cause smoke?

If a valve seal has lost its grip or piston rings get worn, they can cause oil to leak into the combustion chamber. This wayward fuel then mixes with other engine elements and burns, causing white or blue smoke to escape from the exhaust manifold.

Blue Smoke From Exhaust When Accelerating

When blue smoke is emitted from a car's exhaust pipe, this usually indicates that a leak in the engine's valve seals is allowing oil to leak into the combustion chamber where it is being burned along with the fuel. This may be due to natural deterioration or a faulty part.
