Are Lexus Turbo Engines Reliable

Most turbocharged vehicles’ lifetimes cannot be extended with factory-grade turbochargers without sacrificing performance and fuel efficiency. Many turbocharged vehicles struggle in the second half of their useful lives due to failing catalytic converters, problems with oil consumption, a loss of power, and light to moderate exhaust smoke. The lifespan of a turbocharger is typically between 100,000 and 125,000 miles, although extreme driving circumstances, aftermarket parts, and subpar original parts will undoubtedly cause the turbocharger to fail earlier than expected. Due to the high altitude of their domestic manufacturing and engineering facilities, many luxury brands concentrate on the usage of turbochargers. These manufacturers often utilize higher-quality components that should last at least 150,000 miles with normal use and proper maintenance.

Reliability of turbocharged engines

Although, once again, that wasn’t always the case, it appears that when customers reported problems, the issues were more often with the engine than the turbo. Overall, the data indicated that turbocharged engines were dependable and efficient, with occasional problems being caused by a number of factors, including the turbocharger itself and the engine computer.

“In actuality, it can take several model years for automakers to implement such new technology properly.

Since the relative newness of turbocharging systems to each company appears to be correlated, it is expected that as time goes on, these systems will improve and become more dependable and effective for businesses who are more recent entrants to the turbocharged engine industry.

How far can a turbo last?

Turbochargers are very trustworthy. In truth, blown turbos are typically caused by issues with engine lubrication or the entrance of foreign objects, and less than 1% of warranty inspections discover a problem with the turbo itself.

OIL/LUBRICATION

Your car’s engine oil is essentially its life force. It functions to cool them while in use, prevent corrosion, and lubricate important moving parts.

The turbocharger requires a steady stream of pure, high-quality oil. Insufficient oil (oil starvation), the wrong kind of oil, or poor-quality oil will cause pollutants to accumulate in the engine (oil contamination). The inside of the turbo may sustain abrasive damage as a result.

It’s crucial to replace the oil filter and engine oil at the manufacturer’s suggested intervals.

DAMAGED SEALS

Oil will seep into the exhaust system if the seals between the compressor and the engine start to wear out or crack. Because of this, the turbo has to use more effort to raise air pressure.

Overspeeding is another name for this problem. In the end, it will decrease the turbo’s effectiveness and boost output.

FOREIGN OBJECTS/DEPOSITS

The compressor at the front and the turbine at the back are the two basic parts of a turbocharger. Foreign materials like dirt, leaves, and small stones can occasionally enter the turbo through either the compressor inlet or turbine inlet.

The air filter is frequently where the foreign object enters the compressor housing. In contrast, if the turbine is harmed by a foreign object, the issue is typically with the engine.

If foreign items begin to harm the compressor wheels or turbine blades, the turbo’s efficiency will suffer. Your air filter should be serviced and replaced on a regular basis to avoid this from happening. Additionally, you must inspect your turbo for debris.

WEAR & TEAR

Although turbos are intended to last the lifespan of the car (or roughly 150,000 miles), depending on how hard you drive the car and how well the turbo was built initially, it’s likely that they will eventually wear out.

Do turbos reduce engine longevity?

No, modern turbochargers are built to survive as long as the car itself. The fact is that boosted engines need just as much upkeep and attention as a naturally aspirated engine does.

An engine with a turbocharger can last as long as any other engine. Forced induction does indeed add greater pressure and moving parts. A turbo fan, for instance, typically spins at 200,000 to 300,000 RPM. vs a normally aspirated engine, which typically operates at a temperature of 750 degrees Fahrenheit for diesel and 1000 degrees Fahrenheit for gasoline and spins at 8,000 or 9,000 RPM. Consequently, boosted engines are created and developed with these requirements in mind. For the duration of the life of your vehicle, the pistons, cylinders, engine casings, manifolds, and turbo housings have all been designed to resist high pressures and temperatures.

Who produces the most trustworthy turbo engines?

The brands that provide turbocharged engines with greater reliability than non-turbo engines are revealed in a recent Consumer Reports survey. Additionally, it lists the brands with lower reliability.

Consumer Reports (CR) recently conducted a study to determine whether manufacturers offer turbocharged engines that are more reliable than non-turbo engines on average. and which are less trustworthy. According to the survey, six automakers solely provide turbocharged engines, which are more reliable than the typical non-turbo engine. Honda, Lexus, BMW, Porsche, Audi, and Subaru were among these brands. When compared to non-turbo engines, a broader variety of brands offer turbocharged engines that are reliable on either side of the median.

What is a turbo engine’s drawback?

Recall how we said a turbocharger will give you extra power? So, higher power translates to more energy produced each second. This implies that you must exert greater effort when using it. Thus, you need to consume more fuel. Theoretically, a turbocharged engine is no more fuel efficient than one without. Possibly not a significant drawback, but something to keep in mind.

Why, therefore, don’t all engines have turbochargers? After all, more power from a similar-sized engine sounds fantastic! As it turns out, turbochargers don’t always provide the best and most efficient fuel economy. Many offer noticeably inferior fuel efficiency than their competitors. So choosing hybrids and other cutting-edge technologies is the best course of action for saving fuel.

Reliability is also another drawback. An regular engine gains an additional level of mechanical complexity when a turbocharger is added to it. Because more things could go wrong, it needs maintenance more frequently. and hence raise the price of the turbocharged engine. When using a turbocharged engine, you want to squeeze out additional performance from the same fundamental architecture. However, acquiring more also means receiving higher temperatures and pressures, which accelerates the failure of parts.

You can bring the turbochargers to our turbo rebuild company on Long Island if they do break down. We can successfully address and resolve the underlying problems. While staying within your budget, of course. Furthermore, no work will be approved without your consent. Get dependable turbo installation! We’ve been doing what we do for years.

Are turbo engines as durable?

Despite the fact that certain turbocharged engines are dependable, turbo engines frequently have additional issues. A normally aspirated (non-turbo) engine has fewer parts than a turbocharged engine. These include an intercooler, boost control system, vacuum pump, exhaust wastegate configuration, and a more intricate crankcase ventilation system (PCV). Failure of the turbocharger itself is not unusual. More things can go wrong the more parts there are.

Higher combustion chamber pressure causes higher crankcase pressure when the cylinder walls and piston rings deteriorate with increased mileage. This may lead to oil leaks that appear in numerous locations and are challenging to rectify.

Having said that, many turbo engines have a lengthy lifespan. Consider the Mark IV Volkswagen Golf / Jetta’s turbodiesel (from the early 2000s). With proper maintenance, many of them are operating well into 200K miles. Learn more about engine maintenance.

When do turbos malfunction?

Manufacturing flaws are the cause of less than 1% of turbo failures. The three “turbo killers” of oil starvation, oil pollution, and foreign object damage are responsible for the majority of failures.

Over 90% of turbocharger failures are connected to oil, either through oil pollution or oil hunger. Oil starvation is typically caused by clogged or leaking pipelines or by a fitting that hasn’t been primed.

The engine oil has the potential to carry a variety of contaminants into the turbo bearing system and harm it. The most prevalent are fine particles, typically carbon from combustion, and if their concentration rises too much, they act as a very powerful abrasive, gradually wearing down and polishing the running surfaces of the bearing and shaft, widening clearances, and blocking oil feed holes until the oil loses its ability to control the shaft. Typically, this is accompanied by an abrupt rise in noise level, oil leaking past the turbine end seal, which causes oil to burn, and, in cars without a particle filter, significant exhaust smoke.

You should also take into account the following factors because other factors, such as bad driving behavior, can trigger turbo failure:

  • Long-term engine idling can cause the turbine to create a vacuum
  • A hot engine shutdown might result in a buildup of carbon in the turbo, which can cause bearing failure.
  • Excessive engine revving, especially in commercial vehicles like on-highway trucks, can result in the turbo overspeeding and overboosting the engine (this can also happen in naturally aspirated engines), as well as oil starvation.
  • Hard acceleration from a cold start prevents the oil from having time to circulate, starving the turbo and engine bearings of oil.

Without proper calibration, a remanufactured unit would have to employ non-original parts, leading to:

  • A poor effort
  • The cost of installing a second, “new,” turbocharger
  • a lost client.
  • An early failure
  • possible harm to the engine
