Signs of Turbocharger Failure


Signs of Turbocharger Failure

Do you know the signs of turbo failure?

If your turbocharger is operating poorly or sounds like it needs fixed or replaced, there are a few things to keep an eye and ear on.

Acceleration issues

Since prime power is one of the turbocharger’s primary functions, keep a keen eye on your gas pedal. From a delayed response in getting exhaust gases to engage the turbine blades to problems with the turbine blades themselves, a “lag” in acceleration might indicate turbo issues. Slow acceleration could soon turn to hardly any acceleration at all; if the turbo blades are stuck in neutral, they’ll actually prevent much-needed airflow to your engine cylinders.

Check for burning oil

Another sign of turbocharger failure is burning oil. Locate the downpipe, usually at the front of your turbocharger. Disconnect the downpipe, and use an endoscope for a sneak peek inside the actual turbine. If the turbine shows signs of oil, there’s a good chance the turbine piston ring isn’t properly sealed. Oil in the turbine is a sign of gradual failure; if left untreated, your turbocharger will eventually fail.

Irregular or excessing exhaust smoke

Related to the above diagnosis, exhaust smoke could be a sign of turbo failure. What are the common culprits of turbo problems that result in exhaust smoke? Worn internal seals and external cracks in the turbo housing, just to name a few. Keep in mind, exhaust smoke could also mean a bad head gasket, so a thorough engine inspection is necessary. One other quick tip: blue smoke usually indicates turbo lubricating oil being burned off the turbo housing and other engine components.

Check engine light

The check engine light could mean anything from a loose gas cap to serious internal engine issues. And just one of those "serious internal issues" might be the turbocharger. If you have an engine code reader, get it checked immediately. If not, take your car to your local mechanic for a diagnosis. If your check engine light comes on, get it checked ASAP.

Shrieking Noise

A failing turbocharger may produce a loud shrieking noise when the boost is running. The noise comes directly from the engine and sounds like a siren, which usually gets louder the worse the problem gets. Any unusual noise under coupled with any of the above symptoms could be turbo failure.

How to Fix a Turbocharger Failure

Now that you know the signs of turbocharger failure, let’s give you some ways you can get your turbo back to its former glory? Here are two possible remedies:

1. Clean or replace the turbocharger supply lines or fittings. Clogs, grime and other obstacles put a serious damper on power output.

2. Buy a new turbocharger. Preferably, an OEM-grade turbocharger that performs just as well as your old turbo, but at a much better price! Better yet, get a Turbocharger and Installation Accessory Kit for a complete & total installation from start to finish.
