Oil Leaks
- Worn turbocharger oil seals can cause excessive oil consumption and White smoke from the exhaust. Remove center exhaust pipe and examine the turbocharger from the exhaust side. If there is excessive carbon deposits on the turbine exhaust side, oil is leaking from the turbine.
- The turbocharger is not necessarily leaking oil when oil is present on the blower side. Oil most likely has come from oil vapors contained in blow-by gases present in the intake system.
- Oil leaks on the intake side are accompanied by a rattle from the turbine shaft. Remove the turbocharger and check the end and side play.
