What causes Turbocharger Oil Leak?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Turbo shaft seal failure — oil leaks into turbine or compressor housing
- Blocked turbo drain pipe — oil backed up into turbo, then forced past seals
- Positive crankcase ventilation (PCV) valve failure — crankcase pressure forces oil into intake
- Overpressure from blocked oil return — turbo oil exits via shaft seals
- High-mileage turbo with worn shaft — shaft play allowing oil past worn seals

Frequently asked questions
Blue smoke from exhaust when turbo spools up in Hyderabad — is the turbo failing?
Blue smoke specifically on boost (acceleration) indicates oil being pushed into the compressor side via a failed turbo shaft seal or compressor wheel — oil is entering the intake and burning in the engine. This will progressively worsen and eventually cause turbo failure. Metre Per Second diagnoses turbo oil leaks with a borescope inspection of the compressor housing and a turbo shaft play measurement.
