What happens when turbo goes out on diesel?

by Jordan Davidsen

When you are running a diesel engine, a turbocharger can be an invaluable asset to your driving experience. Often referred to as simply a “turbo”, these parts are fitted to an engine in order to increase its performance in a variety of ways. Turbos boost the power of cars and trucks, helping them reach top speeds faster. They enhance the power of your engine without requiring the effort (and cost!) of an entirely different engine. These parts are also fuel efficient and eco-friendly, making for an all around beneficial experience from their addition.

Turbos essentially work by pushing more air into an engine. This happens through the use of exhaust fumes, which function to spin an air pump inside the turbocharger. The influx of additional air increases the combustion efficiency of the engine, which therefore increases its horsepower.

A turbo can be incredibly useful when operating a vehicle. Like any part, though, a turbo is susceptible to failure. Luckily, turbos give off many signs of gradual failure, and these signs can make it easy to know when something is wrong and whether something must be done to fix it.

Slow Acceleration

One of the most prominent features that can tip you off to something being wrong with your turbo is a sudden decrease in acceleration. A turbo’s main function is to provide more horsepower to the engine, and an increase in horsepower should imply an increase in speed; this also includes the acceleration. The power of your engine should be felt when you have a functional turbo, and in turn you should be able to feel a lack of power that signifies your turbo may be failing.

Quick Oil Burning

If you are quickly running low on engine oil, it may be a sign that your turbo is beginning to fail. The turbo can be investigated to look for signs of a leak, or perhaps for any signs of oil deposit in your turbo pipe; regardless, if you can determine that the issue doesn’t have anything to do with the engine itself, it’s likely that a failing turbo is to blame.
