Audi VW Breather Hose - Rein 06J103213D

Product Information

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.

• 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.

About Rein

Founded in 2007, CRP Automotive introduced the Rein Automotive line of OE-quality replacement parts to the aftermarket. And in just two short years, Rein Automotive has become very popular among both warehouse distributors and professional repair technicians. Rein is the German word for “pure”, and has come to be synonymous with quality in the automotive aftermarket. A true dealer alternative.

The Rein brand includes a growing number of “better than OE” parts for selected applications. These parts address known weaknesses and premature failures of factory parts. Many of these replacement and service solutions have been developed with the help of our Innovation Council, a hand-picked group of experienced professional repair technicians and shop owners throughout North America.

All Rein Automotive OE-quality parts are backed by the CRP Automotive standard, and are backed with a ISO 9001:2015 quality management system certification. Each year, CRP Automotive ships thousands of Rein Automotive brand products. And with widespread NAFTA market distribution through strategically placed warehouses in Cranbury, New Jersey and Puebla, Mexico - OE-quality products like Rein Automotive are delivered to customers both faster and more cost-effectively than ever before.

In 2017 Rein partnered with FCP Euro in competing a W204 C300 AER car for the 2017 season. The partnership focused FCP Euro to dive deep into the Rein catalog offering, and hundreds of new products were added and integrated into our catalog. Hundreds of new packages were created not only using the full part pine up of Rein products, but also the entire family of CRP products like Pentosin.

Rein is also an innovative brand, winning numerous trade awards — including multiple new product innovation awards at the annual AAPEX trade show.
