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.

This is the secondary air pump valve for E9x M3 with the S65 V8 engine. Over time carbon builds up inside the secondary air pump valve causing it not to close properly. This failure to close properly can allow exhaust and moisture to get past the valve and enter the secondary air pump, leading to premature pump failure.
