Oil Leaks
- Worn turbocharger oil seals can cause excessive oil consumption and White smoke from exhaust. Remove center exhaust pipe, and examine turbocharger from exhaust side. If excessive carbon deposits exist on turbine exhaust side, oil is leaking from turbine.
- Turbocharger is not necessarily defective when oil is present on blower side. Oil most likely has come from oil vapors contained in blow-by gases present in intake system or defective PCV system.
- If intake side contains oil and a rattle is present, remove turbocharger. Check end play and side play.
