If oil is leaking from your Ford Ranger T6's turbo hose, it is likely engine oil mixed with crankcase vapors. This is normal to a certain extent because turbochargers are connected to the engine's intake system, which can carry oil vapor from the crankcase ventilation system.
However, excessive oil leakage could indicate:
- Blocked or faulty PCV (Positive Crankcase Ventilation) system – Causes excess pressure, forcing oil into the intake.
- Worn turbocharger seals – Allows oil to leak from the turbo into the intake or exhaust.
- Clogged air filter or intake restrictions – Causes oil to back up in the system.
- Excessive blow-by – Could be a result of worn piston rings or engine wear.
Inspect the turbo hoses and connections for looseness or cracks. If the leak is significant, a mechanic should check the PCV system, turbo seals, and overall engine health.
