Periodic inspection and cleaning is recommended for the turbocharger compressor housing (inlet side). Since the fumes from the crankcase are filtered through the air inlet system, oil and combustion by-products may collect in the turbocharger compressor housing.Over time, this buildup can contribute to loss of engine power, increased black smoke and overall loss of engine efficiency. This buildup is only a possible contributor to these factors.If the turbocharger fails during engine operation, damage to the turbocharger compressor wheel and/or to the engine may occur. Damage to the turbocharger compressor wheel could allow parts from the compressor wheel to enter an engine cylinder. This can cause additional damage to the pistons, the valves, and the cylinder head.
Turbocharger bearing failures can cause large quantities of oil to enter the air inlet and exhaust systems. Loss of engine lubricant can result in serious engine damage.Minor leakage of a turbocharger housing under extended low idle operation should not cause problems as long as a turbocharger bearing failure has not occurred.When a turbocharger bearing failure is accompanied by a significant engine performance loss (exhaust smoke or engine rpm up at no load), do not continue engine operation until the turbocharger is repaired or replaced.
An inspection of the turbocharger can minimize unscheduled downtime. An inspection of the turbocharger can also reduce the chance for potential damage to other engine parts.Note: Turbocharger components require clearances that are very precise. The turbocharger cartridge must be balanced due to high rpm. Severe Applications can accelerate component wear. Severe Applications may suggest the need to inspect the cartridge at more frequent intervals.Removal and Installation
