Warning Signs of a Possible Turbo Issue | MCL Mobile Fleet Services | Atlanta, GA.

How Turbos Work

A Turbocharger works by harnessing the kinetic energy contained within the high-temperature exhaust gases expelled from the engine during combustion by capturing it and converting it into useful work to enhance engine performance. These are vital to any turbo-charged commercial vehicle's overall performance. In many cases your turbo will give you warning signs that problems could be looming, and MCL mobile fleet services wants you to be informed.

Whistling Noises

  1. Thrust Bearing Failure: A failing thrust bearing can allow the compressor wheel to contact the compressor cover under boost, creating a whining noise. This type of mechanical failure is significant and requires prompt attention

  2. Turbo Bearing Failure: Similar to the thrust bearing, the turbo's main bearings can fail, leading to a whistling or squealing noise. This indicates serious turbocharger damage and necessitates repair or replacement

  3. Compressor Speeding Up: The turbo whistle is essentially the sound of the compressor inside the turbocharger speeding up. This sound can become more noticeable if there are issues with the turbo system

  4. Boost Leak: A high-pitched whistling sound may also indicate a boost leak in the turbo system. Boost leaks occur when the pressurized air escapes from the turbo system's intended path, leading to performance losses and the characteristic whistling noise

Increased Oil Consumption

  1. Excessive Bearing Clearance in the Turbocharger: This condition can lead to oil leaking into the combustion chamber, where it is burned, thus increasing oil consumption.

  2. Blocked Oil Return Line on the Turbocharger: A blocked oil return line can prevent oil from flowing back into the engine from the turbocharger, causing it to accumulate and burn within the turbocharger assembly.

  3. Worn Injection Pumps: Worn or malfunctioning injection pumps can lead to improper fuel delivery, affecting the combustion process and indirectly leading to increased oil consumption.

  4. Internal Leaks: Internal leaks, which may not be immediately obvious as they don't result in visible oil leaks outside the engine, can cause oil to be burned within the engine's combustion chamber, increasing oil consumption.

  5. High Oil Pressure: Incorrect oil pressure settings or a faulty relief valve can result in high oil pressure, which might contribute to increased oil consumption
