How Long Does A Turbo Last On A Diesel?

Large heavy-duty turbo diesel engines are expected to last 500,000 miles or more on average. Turbo engines are often stronger than naturally aspirated engines, therefore if properly maintained, they will last a long time.

How many miles will a turbo diesel engine last?

Your car’s gasoline engine should last roughly 200,000 miles before it requires a major maintenance or you need to purchase a new vehicle. Diesel engines, on the other hand, may run for 1,000,000-1,500,000 miles without having any serious maintenance. In fact, a well-maintained diesel engine can last for 30 years or more on the road.

According to Capital Reman Exchange, there are three key factors for a diesel engine’s lifetime, endurance, and reliability:

A diesel engine is gear-driven in design. Gears, unlike other parts that might be broken or damaged, are easy to repair and never lose their timing. Gear-driven water and oil pumps are available on most diesel automobiles. Parts and components are less likely to fail as a result of this.

Diesel-powered vehicles are typically built with heavy-duty components that can withstand the vehicle’s power, resulting in less wear and tear on all parts of the engine.

Diesel engines are also fantastic since they are self-cooling, which means they have a far lower possibility of overheating. There are multiple sensors and thermostats in use, which means that if one fails, the engine will not overheat. A steady supply of coolant flows freely through the engine thanks to many piston-cooling nozzles.

Compression ignition is used by a diesel engine to use its fuel to power itself. This happens when diesel fuel and air are squeezed to the point that heat is generated, resulting in spontaneous combustion. This spontaneous combustion, according to Digital Trends, is significantly more favourable for a long-lasting engine.

How do I know if my diesel turbo is bad?

A turbocharger, commonly known as a turbo, is a sophisticated device that increases the power of an engine. Many automobile manufacturers now use turbos to give the same power seen in larger, more powerful cars while allowing consumers to enjoy the financial and environmental benefits that come with having a smaller engine, thanks to the implementation of UK emissions rules.

Turbos, despite being meant to last as long as the car, are susceptible to deterioration over time. Find out what causes turbo failure and what you can do about it in the sections below.

How does a turbo work?

Your engine generates power by combining fuel and air. Adding extra air to your engine is one of the simplest methods to boost its power while keeping your operating expenses low. Your turbo does this by spinning an air pump with the exhaust. This air pump forces more air into your engine’s cylinders, resulting in a significant increase in horsepower.

What causes turbo damage

  • Engine oil is required for the effective operation of your turbo. A lack of oil, the incorrect grade of oil, or poor quality oil will cause carbon deposits and impurities to build up in the engine, causing abrasive damage to the turbo. To prevent this buildup, we recommend using a high-quality, 100% synthetic oil.
  • The age and mileage of the vehicle. Although turbos are built to last the life of the vehicle, they do have the potential to wear down over time. This could be due to the quality of the turbo that was initially installed, or it could be due to how hard you drive the car.
  • Seals that are cracked or worn out. Oil will seep into the exhaust system due to damaged seals between the compressor and the engine, forcing the turbo to work harder to increase air pressure.

What to do if you have a blown turbo

If you suspect you have a blown turbo, have it checked out by a trained technician as soon as possible. The longer you wait, the more harm will be done, and the cost of repairing the problem will increase.

We provide a Diagnostic Check for £49.99 at Halfords Autocentres. To diagnose and advise on any necessary repairs, our ATA-trained specialists use state-of-the-art automotive diagnostic test equipment. If your turbo needs to be replaced, you will be given a detailed quotation before any extra work is done. After that, our crew will install the proper Original Equipment (OE) turbo for your car.

How often do Turbos need to be replaced?

Between 100,000 and 150,000 miles, most turbochargers need to be replaced. If you take good care of your automobile and receive regular oil changes, your turbocharger could last even longer.

What happens when the turbo goes on a diesel?

When a turbo breaks, the oil seals on the rotor shaft are frequently the first to fail. This draws engine oil into the inlet tract, allowing the engine to run on its own oil.

Should I buy a diesel with 200k miles?

Diesel trucks, on the whole, are sold with higher mileage than the average used vehicle. It’s not unusual to come across a used diesel truck for sale with more than 200,000 kilometers on it. Although diesel engines are generally more reliable than gasoline engines, excessive mileage remains an issue.

Is 300k miles alot for a diesel?

When it comes to mileage, according to Prosource Diesel, diesel vehicles frequently receive better mileage than gas trucks since their engines are more durable. As a result, according to Prosource Diesel, it’s not uncommon to find a used diesel truck with more than 200,000 kilometers on the odometer. There’s a good chance you’ll stumble across a used diesel vehicle with 300,000 miles on the clock.

What constitutes excessive mileage in the case of specific diesel engines? According to Prosource Diesel, a secondhand diesel truck with a Cummins or Duramax engine with more than 350,000 kilometers is considered excessive mileage. For a Powerstroke diesel engine, anything above 350,000 miles is considered high mileage.

How long should a turbo last?

Turbochargers have a high level of dependability. In fact, only around 1% of warranty checks uncover a problem with the turbo; instead, blown turbos are typically the result of engine lubrication issues or the entrance of foreign items.

OIL/LUBRICATION

Your car’s engine oil is literally its life blood. It keeps important moving parts lubricated, protected from corrosion, and cool while in use.

The turbocharger requires a steady supply of clean, high-quality oil. A shortage of oil (oil starvation), the wrong grade of oil, or poor quality oil will cause pollutants to build up in the engine (oil contamination). This may cause abrasive damage to the turbo’s interior.

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

DAMAGED SEALS

Oil will seep into the exhaust system if the seals between the compressor and the engine become old or fractured. As a result, the turbo is forced to work harder in order to increase air pressure.

Over-speeding is another term for this issue. In the end, the turbo’s efficiency and boost will suffer as a result.

FOREIGN OBJECTS/DEPOSITS

A turbocharger consists of two basic components: the compressor in the front and the turbine in the back. Foreign objects such as dust, dirt, leaves, and small stones can sometimes enter the turbo through the compressor or turbine inlet.

The air filter is usually where the foreign object enters the compressor housing. When a foreign object damages the turbine, however, the problem is usually caused by the engine itself.

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. Check for debris in your turbo as well.

WEAR & TEAR

Turbos are supposed to last the life of the vehicle (about 150,000 miles); nevertheless, depending on how hard you drive the car and the turbo’s original construction quality, they may wear down over time.

How long do turbo engines last?

When it comes to turbochargers, how long do they usually last? Turbos last an average of 150,000 miles (or around 50,000 miles on a standard automobile), but they can wear down over time depending on how hard you drive it and the quality of the original build.

Can a turbo be repaired?

Yes! Almost all turbocharger problems may be fixed in the right hands. It’s more vital to figure out what’s wrong with the turbocharger and how to fix it. Here are a handful of important repair recommendations to keep in mind when diagnosing turbocharger issues.
