White Exhaust Smoke

Sustained engine operation with faulty bearings will result in failure of oil seal, which can permit engine oil leakage into exhaust and intake pipes. Engine oil leakage from turbocharger into exhaust pipe or intake pipe will result in White-colored exhaust. If this occurs, inspect for clogged, crushed or deformed oil return pipe. Leakage may also be due to worn piston ring (seal ring) in turbocharger. Also check for a plugged crankcase ventilation system.
