What common faults could cause blue smoke?
Blue smoke from the exhaust: Oil is being burned. There are a number of potential causes, with the more severe being worn valve seals, piston rings or turbochargers. Grey smoke from the exhaust: This could be excess oil, a PCV valve failure or a transmission fluid leak on automatic cars.

What causes blue smoke from 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 misfire cause blue smoke?
The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs.
What causes blue smoke from a diesel engine?

How do you know if your fuel injector is bad?
You might also notice a drop on the fuel gauge. A faulty fuel injector can lead to a significant drop in fuel economy. This is because the ECU is calling for more fuel from the injector but not receiving it in the combustion chamber. The less fuel reaches the engine, the lower your fuel economy.
Can a bad glow plug cause blue smoke from exhaust?
Once the engine is warmed up, the use of the glow plug is not necessary as the heat of the engine makes ignition of diesel fuel. If a diesel engine has a bad glow plug, it will create blue smoke at startup until it has warmed up. What Makes Blue Smoke From Exhaust When Accelerating?
Can a bad fuel injector cause a car to stall?
If too little fuel is reaching the combustion chamber, the ECU will stop the engine, causing a stall. Engine stalling as a result of a failed injector normally occurs when the nozzles are badly blocked or when there’s a fuel leak where the injector connects with the fuel lines.
