Crankcase ventilation blockage

A blocked crankcase ventilation system is a common problem. The blockage affects the engine's performance. This blockage occurs in the crankcase ventilation hose, where oil residues and moisture accumulate. During winter, the moisture freezes, causing the hose to crack. The oil also deteriorates the rubber of the hoses.

One symptom of a faulty ventilation system is a sputtering engine. Other symptoms of a defect include:

an illuminated engine warning light,

fluctuating engine speed,

high oil consumption,

a hissing sound near the crankcase.

Experiencing any of these issues? Check your crankcase and replace the crankcase ventilation system if necessary.

Crankcase ventilation

The crankcase ventilation system captures blow-by gases from the crankcase and vents them correctly. It's crucial that this system functions properly, as it prevents harmful gases from being released into the atmosphere. Instead, these gases are directed along with clean air through the intake manifold and into the engine's combustion process. A faulty crankcase ventilation system can lead to engine problems. You can find individual ventilation components or complete crankcase ventilation kits at Winparts.
