3.2 Power Stroke (Transit): oil leak, oil consumption or rising oil level

3 documented failures on this engine list this among their signs. They are ordered from the most widespread down. Each one shows the signs in its record's own words, how to tell it from the others, the usual fix and any recall or bulletin.

  1. Engine oil leaks / crankcase ventilation hose Common · 2 recall/bulletins
  2. Common-rail injectors / injection pump faults Occasional · 4 complaints · 2 recall/bulletins
  3. Turbo / VGT faults (oil in exhaust after turbo) Occasional · 1 complaints

1 Engine oil leaks / crankcase ventilation hose
aggregated How widespread: Common

How it shows up

  • engine oil leak traces on the front/side of the engine
  • low oil level between services
Its other signs
  • oil mist around the crankcase vent hose

How to tell it apart

  • degrease and re-inspect to find the true source (valve cover, vent hose, front seals)
  • check the crankcase vent hose for collapse/seepage per 23N01
  • verify oil level history before hardware

Usual fix

crankcase ventilation hose assembly replacement (23N01) and/or gasket/seal correction

Recalls and bulletins

23N01SSM 47020

2 Common-rail injectors / injection pump faults
aggregated How widespread: Occasional 4 NHTSA owner complaints match it, out of 10 checked

How it shows up

  • fuel dilution of the oil over time
Its other signs
  • rough running / misfire-style shake on a diesel (cylinder imbalance)
  • hard start or extended crank
  • MIL with injector-circuit or rail-pressure DTCs

How to tell it apart

  • cylinder-balance test / injector buzz test per the service procedure
  • rail pressure desired-vs-actual logs; check for dilution (oil level rising)
  • verify fuel supply (filter, water separator) before injector replacement

Usual fix

injector(s) replacement with the calibration/checks per procedure; pump-side repair where the rail pressure fault points there

Recalls and bulletins

16V-618TSB 16-0099

3 Turbo / VGT faults (oil in exhaust after turbo)
aggregated How widespread: Occasional 1 NHTSA owner complaints match it, out of 10 checked

How it shows up

  • oil traces in the exhaust downstream of the turbo
Its other signs
  • underboost / reduced power DTCs
  • whistle or bearing noise

How to tell it apart

  • log boost desired-vs-actual; check the actuator and vane movement
  • inspect shaft play and the oil drain path
  • rule out charge-path leaks before turbo replacement

Usual fix

turbocharger replacement with oil-supply/drain correction; actuator where the control fault is isolated

Order: how widespread each failure is in its record (near-universal, very common, common, occasional, rare), then the number of NHTSA owner complaints that match its keywords. Complaint counts are keyword matches, not a manual review of each complaint. A symptom listed here means the failure is documented with that sign; it is not a diagnosis of your truck.
