All Caterpillar Engines Equipped With Turbochargers
Turbocharger bearing failures can cause large quantities of oil to enter the air intake or exhaust systems. Loss of engine lubricant can result in serious engine damage. Minor leakage of a turbocharger housing under extended low idle operation will not cause a problem as long as there is no turbocharger bearing failure. When a turbocharger bearing failure is accompanied by a significant engine performance loss (exhaust smoke or engine speed up at no load) do not continue engine operation until turbocharger is repaired.
