Oil Leaks - Turbocharger
1989 Subaru Justy DLSECTION Oil Leaks - Turbocharger
- 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 defective 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 or defective PCV system.
- If intake side contains oil and a rattle is present, remove the turbocharger. Check the end play and side play.
