Why do turbo cars smoke

Alternatively, if your vehicle is turbocharged - which is becoming much more common on modern cars - then the cause might be traced back there. A turbocharger works by forcing air into the combustion chamber. Like all moving components in an engine, it uses oil for lubrication and any seal problem may cause that oil to leak into the turbo and be blown into the chamber. Turbochargers are actually considered to be pretty reliable pieces of kit, so blue smoke is more likely to be caused by oil leaks in the engine proper.

Thick grey smoke could be the result of a couple of issues. Like blue smoke, it can be an indication your car is burning oil or that the turbocharger is playing up see above for possible suspects.

It can also indicate that transmission fluid — the stuff that lubricates the components of the transmission system - is leaking and burning off. Clouds of white smoke belching from the tailpipe is another issue altogether. These problems could include a coolant leak, a cracked engine block or an issue with the head gasket — all of which are of major concern.

The head gasket, for example, is the component that sits between the engine block and the cylinder head — the two pieces that form the core of the engine and are where the pistons, cylinders and combustion chamber are housed. When it comes to your engine, this is not an exaggeration.

And check if there is an orifice or not. Another case, even the actuator or the wastegate is working fine, if the spring is weak, it will not have the boost up because the valve open for exhaust pressure. Blocked exhaust system If there is block for the Exhaust manifold, turbo charger, extension, front pipe, catalyzer, and muffler the boost pressure will not go up. The leakage in the exhaust system If there is gas leakage for the exhaust manifold or turbo installed flange, the boost pressure will not go up.

You will probably notice when this happen because of the leaking air sound. If you don't find any problem of I to VI, it could be the problem of engine. If you find no problem in the engine, please check the turbo charger. You will hear the big blow sound when it starts to open if the wastegate exit is deformed or fully open. If you don't find any problem of I to V, it could be the problem of engine. Take out the intake pipe of the turbo charger and turn the rotor with your finger.

Be careful not to turn the engine on. If the rotor turns: Wheel could be broken. The compressor wheel or turbine wheel is deformed or broken. Sometimes you can see it without taking off the turbo charger, but sometimes you can't see it if you take off the housing. If it's deformed or damaged, you can hear a weird sound.

If you keep this for a long time, wheel and housing will interfere because of unbalance and finally the turbo charger will break down.

So if you hear the sound of a weird sound, take the turbo charger and have a check. Also if the bearing is turning in friction, the rotor is not properly moving. For both conditions, you need to take it off and have an inspection. If the rotor is not turning: The turbo charger rotor is stuck or interfering. The rotor will have lock or malfunction of turning by the seizure the ball bearing. Also the long term oil leakage occurs, it will get carbon because of the heat of the turbine and cause the rotation malfunction by the turbine and the rotor.

There a case where the some waste stuck in the turbine and housing or shroud that causes the lock. In this case, you can confirm with your finger and don't have to take off the turbo charger.

However turbo charger is broken so take it off and have an inspection. When taking off the turbo charger, be careful to confirm the list below as carefully checking where the problem is. Check the unusual bolts, nuts and hose. Check for contaminant usually caused for turbo charger damage III. Check for Heat discoloration IV. Check for oil or coolant water for leakage or bad contamination.

If you notice above matter, don't disassemble and bring the turbo charger to the shop where you purchased. If a dirt goes into the turbo charger, it will be a clearance failure and will damage the shaft receiver and bearing surface.

In this orifice will have a dirt or sludge stuck into and have the oil film breakage and seizure. The resulting combination of burning oil and gas can cause blue smoke. This process gives your engine another chance to use any uncombusted gases, thus improving your gas efficiency.

When your PCV gets stuck in the closed position or becomes blocked, the imbalance of pressure in the crankcase can cause oil to get into the engine. The burning oil in the engine leads to the blue smoke coming out of your exhaust. If your car has a turbocharger, a blown-out turbo may be causing the blue cloud behind your car. A blown-out turbo can be identified by a broken or damaged oil seal. There, oil mixes with fuel and leads to blue smoke. With modern engines lasting so long these days, it can be easy to forget that even the best-constructed engines can wear out.

The transmission modulator is a part in older cars that detects your current engine load in order to most efficiently shift from gear to gear. If your transmission modulator goes bad, it can lead to your engine sucking in transmission fluid. Once inside your engine, transmission fluid and fuel burn and cause blue smoke to come out of your exhaust.

There are many potential reasons that cause blue smoke to come out of your exhaust.
