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.

Benefits:

  • Prevents Freezing Issues: Reduces the risk of oil separator failure in cold weather conditions.
  • Eliminates Oil Leaks: Helps prevent leaks caused by frozen oil separators.
  • Ensures Proper Ventilation: Maintains effective purging of oil vapor from the engine block.
  • Durable Construction: Built to withstand harsh weather conditions and engine stress.
  • Direct Replacement: Designed to fit seamlessly with BMW N63 4.4L engines.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. This oxygen sensor for BMW's with the N52, N54, and N55 3.0L engines. This 490mm bank 2 oxygen sensor is mounted after the catalytic converter.

The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

The Pressure Control Ventilation (PCV) valve is designed to route high-pressure blow-by gases from the crankcase into the intake manifold, relieving excess pressure while recycling gases back into the combustion process. When the PCV valve fails, it can lead to excessive oil consumption, rough idle, and stored engine fault codes. Replacing a worn or faulty valve restores proper crankcase ventilation, smooths out idle, clears codes, and helps keep your engine performing at its best.
