When you drive your BMW, the engine draws air in and out of the crankcase through a ventilation system, which helps prevent condensation from forming within the engine of your car. This system is comprised of two components: a crankcase vent valve and a positive crankcase ventilation (PCV) valve. Rubber hoses are used to link one of the valves to the other; these hoses eventually wear out and need to be replaced. YOUPARTS PCV Valve Positive Crankcase Ventilation has been painstakingly constructed to provide a seamless integration with the vehicle. Because we have a long history of inventing and producing high-quality aftermarket parts, you can be certain that YOUPARTS PCV Valve Positive Crankcase Ventilation will be available for purchase for many years to come
