CCV/PCV Breather Hoses for BMW X Series G07 X7 (2019+)

BMW N63 4.4L Vent Pipe

The BMW N63 4.4L Vent Pipe addresses common issues with oil separators freezing in cold weather conditions. This problem often occurs if the vehicle is driven before it is fully warmed up, leading to a howling noise and multiple oil leaks. The crankcase breather valve in the vent pipe purges oil vapor from the engine block into the valve cover. However, condensation can sometimes cause the valve to freeze, which may result in the oil separator system failing, cracking, or disintegrating. This replacement vent pipe ensures proper function and prevents costly damage by maintaining the integrity of the oil separator system.

• Ensures Proper Ventilation: Maintains effective purging of oil vapor from the engine block.
