Turbo Trouble

Causes:

  • Low engine oil levels
  • Obstructions in oil feed lines
  • Build up of burnt oil in center housing
  • Excessive Temperature
  • Inferior oil quality.
 Consequences:

  • Excessive wear of journal bearings, thrust bearing, and thrust collar.
  • An imbalance causing excessive wear to rotating components.
  • Wear of sealing surfaces of back plate and thrust collar.
  • Piston ring failure or leakage.
 Symptoms:

  • Oil leakage
  • Noise
  • Loss of power
  • Excessive smoke
  • Excessive oil consumption

 

Causes:

  • Saturated oil filter
  • Recycled Oil
  • A rebuilt engine with impurities within the oil passages.
  • Burnt oil from high temperatures.
  • Residue from incomplete combustion.
 Consequences:

  • Scoring and wear of journal bearings
  • Scoring and wear of thrust bearing and thrust collar.
  • Imbalance
  • Failed components
 Symptoms:

  • Oil leaks
  • Noise
  • Loss of power
  • Excessive Smoke
  • Excessive oil consumption

Causes:

  • Materials ingested into either the compressor, or turbine side of the turbo.
  • Damage to the compressor side suggests an insufficient/dirty air filtration system, or a damaged air intake tubes.
  • Damage to the turbine suggests damage to the engine such as parts of the pistons, or valves.
 Consequences:

  • Damage to the wheels.
  • Imbalance to the rotating assembly.
  • Excessive wear to the rotating assembly.
 Symptoms:

  • Loss of power.
  • Noise
  • Excessive smoke.
