Bad crankcase breather hose symptoms

Issues with the crankcase breather hose can manifest in various problematic symptoms. These include oil leaks, engine oil pollution, irregular idling or stalling, excessive oil consumption, heightened emissions, engine knocking or pinging, and decreased overall engine efficiency. The root cause is that a damaged or clogged vent hose can lead to pressure imbalances in the crankcase. This, in turn, forces oil out through unintended openings, contaminates the oil supply, and disrupts the engine's proper breathing and combustion.

Addressing problems with the crankcase breather hose is critical for maintaining engine health and performance. Any of the symptoms mentioned should prompt a thorough inspection and potentially replace this important component.

Crankcase breather hose replacement

  1. Locate and disconnect the old hose: Find the breather hose, typically running between the valve cover and air intake, and carefully disconnect it from both ends, loosening any clamps or fasteners.
  2. Inspect the old hose: Examine the removed hose for any cracks, holes, or signs of deterioration that may have caused the issue.
  3. Install the new replacement hose: Obtain the correct replacement hose and gently push it onto the valve cover and air intake connections, securing it in place with any necessary clamps or fasteners.
  4. Secure the new hose: Use zip ties or small hose clamps to hold the replacement breather hose firmly in place and prevent any movement or rubbing against other engine components.
  5. Check for leaks and clear codes: Start the engine and inspect the connections for any oil or air leaks, tightening if needed. Then use an OBD-II scanner to clear any trouble codes that may have been set by the old, faulty hose.
