BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. Don't forget to order a valve cover gasket, throttle body gasket, and a new intake boot to make your separator change easier and more comprehensive.

The engine crankcase breather hose is a vital part of the Positive Crankcase Ventilation (PCV) system, responsible for directing pressurized air from the engine crankcase to the air/oil separator, also known as the PCV valve. This separator removes oil vapors from the air, allowing the oil to return to the engine while feeding the filtered air back into the intake system to support efficient combustion.

As a byproduct of the combustion process, positive crankcase pressure naturally builds up in the engine. The breather hose operates under constant exposure to heat, pressure, and an air/oil vapor mixture, making it prone to wear and failure over time. Ensuring the breather hose is in proper working condition is crucial for maintaining engine performance, adhering to emissions standards, and preserving the functionality of the PCV system. Promptly replace this component at the first signs of damage or degradation to avoid further complications.
