Product Information
Completely refresh your BMW’s crankcase breather system
Your BMW’s crankcase breather system is designed to vent oil vapor from the crank of the engine to the intake manifold where it can be burned by the engine. Faulty PCV systems can cause several performance issues and component failures. Clogged PCV valves can cause high crank pressure which can destroy engine seals. Clogged or condensation filled hoses can freeze and crack which can cause oil and vacuum leaks. The end result of these types of failures is usually vacuum leaks and performance issues.
We recommend regular inspection of your BMW’s PCV system and to replace the system as a whole if there are any leaks or visible wear. You can normally identify this systems failure by leaky hoses or a cracked valve. We also highly recommend thoroughly cleaning the engine oil dipstick to remove any clogging that may have built up from oil film flowing through the return hose.

Engine Crankcase Breather Hose Kit
An engine crankcase breather hose is a primary component of an engine’s positive crankcase ventilation system, funneling pressurized air from the engine crankcase to the air/oil separator, also known as the PCV valve. The PCV valve, or air/oil separator, is designed to capture and remove oil vapors from the pressurized crankcase air, allowing them to drain back to the engine, while the pressurized air is fed to the intake side of the engine and utilized as part of normal combustion.
An engine develops positive crankcase pressure as a byproduct of the overall combustion process. Because of the combination of pressure, heat, and the air/oil-vapor mixture traveling to the PCV valve, the engine crankcase breather hose is a common failure item within the PCV system and is crucial to your car’s engine’s performance and emissions compliance.
Engine Crankcase Breather Hose Kit Failure Symptoms
- Cracks breaks, leaks: Over time, your engine crankcase breather hose can be easily damaged because of constant exposure to oil vapors, heat, and pressure from the engine. The engine oil can slowly break down the plastic or rubber materials, eventually causing an air leak. This can happen naturally, or because it is damaged from external contact.
- Broken connectors: Plastic can become brittle over time, especially when exposed to heat and oil, and it’s easy to break one of the securing clips or connectors for a PCV hose, either during removal or during other services.
- Broken or damaged hose: Soft rubber or brittle plastic, depending on the material of the hose, can result in an obvious hole or split in an engine crankcase breather hose, usually accompanied by one of the other faults listed below.
- Check Engine Light: Excessive unmetered air from a failed engine crankcase breather hose can result in a CEL for an air intake leak fault or other airflow-related diagnostic trouble codes.
- Misfire: A severe air intake leak can cause rough running and an engine misfire, a common side effect of a bad engine crankcase breather hose or PCV Valve
- Oil residue on or around the hose or adjacent components: As engine crankcase vapors escape from a faulty engine crankcase breather hose, the hose, engine block, and adjacent components are likely to become visibly soiled with oil residue and moisture. In the most severe cases, you will smell burning or burnt oil, and you may need to degrease the area to determine the exact cause of the oil residue.
