Product Description
This Arrowhead valve non-return one way V/cover is a crucial engine pressure control valve designed for use in Audi and Volkswagen vehicles. It helps maintain correct crankcase pressure by allowing gases to flow in only one direction, preventing unwanted backflow into the engine. Proper operation of this valve supports engine efficiency and reduces the risk of oil leaks or pressure-related issues.
Compatible with a range of Audi and Volkswagen models, this part is typically installed on the valve cover and connects to the engine’s ventilation system. To ensure correct fitment, please confirm your vehicle’s model, year, engine size, and engine code before ordering.
A failing or blocked non-return valve can lead to symptoms like rough idling, increased oil consumption, loss of power, engine warning lights, or even oil leaks around the valve cover. You may also notice whistling noises or increased pressure inside the engine if the valve is not functioning correctly.
Replace this valve if you detect any of these symptoms or during routine maintenance, especially if your vehicle has high mileage. Timely replacement helps prevent more serious engine issues and maintains optimal engine performance.
Order with confidence from MiMi Auto Parts. We offer nationwide delivery across South Africa and are committed to supplying the correct parts for your vehicle. Always double-check your vehicle details before purchasing to ensure compatibility.
