Purpose of the Part

The oil breather separates oil mist from gases produced inside the engine crankcase. It allows crankcase gases to vent while returning separated oil to the engine, helping control internal pressure, reduce oil loss, and protect engine seals from excessive pressure buildup.

Issue Symptoms / When to Replace

Possible signs of crankcase breather problems may include:

  • Excessive crankcase pressure
  • Oil leaks around engine seals or gaskets
  • Excessive oil mist or leakage from the breather outlet
  • Increased engine oil consumption
  • Crankcase ventilation-related fault codes

These symptoms may also result from excessive engine blow-by, blocked ventilation lines, or other engine issues. Proper diagnosis is recommended before replacing the breather assembly.

Brand Information

International Navistar has incorporated advanced crankcase ventilation technology into its heavy-duty diesel engines. The Alfdex oil separation technology used in these systems originated from a 2004 collaboration between Alfa Laval and Haldex, combining centrifugal separation expertise with commercial vehicle engineering to reduce oil mist and crankcase emissions.

Installation Notes
  • Oil Return: Inspect breather oil return passages and ventilation lines for restrictions or sludge buildup before installation.
  • Sealing: Ensure the required seals are correctly installed to prevent oil leaks and improper crankcase ventilation.

How to Identify an OEM Part

Look for the Alfdex logo molded directly into the breather housing. This is a key manufacturer identification feature found on the original component.
