Emissions System

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking. 

The plastic hoses and oil separator can crack or become faulty, leading to vacuum leaks or oil leaks. This is caused by the stress the plastic components are exposed to during heating and cooling cycles, especially if the vehicle is not brought up to operating temperature during driving in cold weather climates.

This kit includes the needed hoses, oil separator, mounting grommet, and hardware.

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 part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. 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.
