5 signs that your turbo is about to fail, and what to do about
Virtually all currently equipped cars for sale turbo engines. All they used diesel turbos for years. The chances are that your car has a turbocharger. Now we have explained how a turbo works and what it does. I have also given advice to properly care for and extend their life. In this article we tell how to detect the turbo is about to fail, or already failing. Also we show you how to prevent failures turbo. Hopefully, the economic setback will not be so great.
turbochargers They may reach 200,000 rpm turn, and high-performance cars, its temperature can reach 1,000 degrees Celsius. Its smooth functioning depends on proper performance and efficiency of your car. Turbos and its moving parts are tough, but no turbine supports continuing abuses for years without consequences. If you do not treat her right, break. As simple as that. And if he breaks the bill will not be small. In fact, a bad break turbo can end the life of your engine.
The good thing is that before breaking, the turbo shows clear symptoms. It is like a serious illness: you catch it early can save your life in the car. How I can know that the turbo is failing or is about to do? Stay with us.
1) White smoke / blue, and high oil consumption
As you know, all engines consume oil, albeit barely noticeable. But If oil consumption of your car fires, serious trouble ahead. Turbocharger health is closely linked to oil the car. For the turbocharger turbine can rotate at 200,000 rpm, the shaft rotates bathed in oil. This axis - also called turbo spool - is surrounded by special caps, turning inside oil-bath. These caps can develop clearances.
These clearances cause a loss of tightness of the shaft, causing the oil that lubricates the intake and enters be burned within the engine. Your car has not elected a new pope, it is burning oil. Burnt oil manifested as a white smoke with blue dye and a characteristic odor emanating tailpipe.
What should I do?
Stop immediately, if possible, and call the crane. Replace caps or turbo shaft is better and more affordable than wait for a total system failure. Check that the engine still has an acceptable level of oil if you slow to notice the "white smoke". If caps fail so loud, it can occur the fearsome feedback. The engine will start to drink their own oil as fuel, faster and faster. The engine will peak rate, and it will stay there until the last drop of oil, self-destructing by mechanical scuffing is drink. It is an extreme case, but it happens.
2) Performance lower than normal, or jerks
If your car has a VGT - there is little gasoline turbo with variable geometry, all practice are diesel - the mechanism that varies its geometry can be damaged. Variable geometry seeks greater performance of the car in any regime, changing the angle of the turbine blades. This angle is changed in most vehicles by electromechanism. Because of the high temperatures generated, the electromechanism be damaged.
The sooting - combustion byproduct - so you can agarrotar. This soot - especially diesel cars - can result from heavy use in town or a regular driving at a very low rate. As we have already explained, this is not good for your car antipollution systems. You'll notice that the car has lost dozens of horses, their performance is much lower than usual. Many cars come into safe mode, and warn of "engine failure" in its implementation.
If you notice that the car gives intermittent jerks, the turbo wastegate - driven by a pneumatic lung - it may be damaged. The car could go into safe mode. Again, not a fault especially problematic.
What should I do?
Go to your shop, if the car will let you. When in doubt, take it in tow and avoid greater evils. The workshop descarbonizarán or replace the mechanism. Fortunately, is not a malfunction face and turbo will function properly after repair. Motor physical integrity would not be compromised. Preventively a decarbonization turbo - and EGR, especially diesel cars - it is convenient, especially if your car is getting on in years and perceive some gradual decline in performance.
Replacement of parts of the discharge valve is also expensive.
3) in the engine Silbidos
Listen to your car. Almost all mechanical failures can be detected paying attention to the engine, and its sound. If you hear the engine snorts, or the sound becomes more "fat" than usual when accelerating, there may be a loss of pressure in the system. Chances are that one of the sleeves turbocharger - or clamp - has slackened or developed any cracks. These cracks can appear only under high load, and can be invisible to the naked eye, hence the importance of hearing.
Some cars enter safe mode to pressure losses in the supercharging system. You may notice a decrease in performance of the car, without being excessive.
What should I do?
The extent of damage is small, but it must be remedied. Fortunately, a new metal clamp or a new sleeve does not carry a huge economic cost. They are inexpensive replace parts is simple. regularly checks the condition of the car sleeves and monitors that have no cuts or folds. If your car is in years, considered a preventive replacement of some sleeves. They are not expensive and will save you headaches.
4) Strange noises, mechanical howls and "vacuums" under the hood
Bad business, very bad business. If your engine starts to sound like a vacuum or low acceleration strange noises, and both symptoms are accompanied by a patent loss benefits, we have bad news for you. Turbo shaft has developed sags and Turbine blades have come into direct contact with the casing... tens of thousands of rpm. Given their revving, its disintegration is guaranteed. These metal pieces end up in the engine cylinders, causing the destruction of mechanics.
Just thinking about pieces of metal inside the engine - under enormous pressure - should give you chills. If you're lucky - you turn off the engine immediately notice the looming carnage - breaking the turbo will not affect the rest of the engine, but the probability of mechanical damage to other engine components is high in this case. Some turbos can give warnings of imminent failure, but no breakages that occur without warning, even gently rolling highway.
What should I do?
For once, and turn off the engine. Hopefully, there will only be broken turbo and will not affect other engine components. In the worst case, it will play vital engine components change, or even the engine completely. A turbo costs about 1,000 euros, but it is labor which greatly increases the cost of the damage. His replacement is not as fast as an oil change, not at all. Why should periodically workshop check that the turbo does not have any clearances.
A few tips to extend the life of your turbo
We have already published an article on tips to protect your engine turbo, which we have today added several preventive maintenance tasks, as a decarbonization of turbo or check clearances on its axis. However, it is best to keep your turbo will go to heaven of the turbos is to follow these guidelines:
- Wait a couple of minutes to start and to reach your destination, idling. This normalized temperature and turbo prevents the shaft oil charring, creating sediment and abrasive particles that will ruin the spool and cause oil leakage. Stops after motorway driving are particularly sensitive.
- Use high quality oil. It seems obvious, but the truth is that saving on cheap oils - with lower lubricating properties and rapid deterioration - is completely nullified by a broken turbo prematurely.
- do not step on the car until the oil is not at the optimum temperature. Falls drawer, you want to ensure that lubrication properties oil to be perfect, and the proper viscosity. This also benefits the other components of engine friction.
