Overview

The RB N54 PCV Valve is an upgraded replacement PCV valve designed for the N54 Engine. It is recommended for high-performance or higher mileage N54 engines. The OEM plastic PCV valve often leaks pressurized conditions into the crankcase, which can be exacerbated by a cracked valve cover, loose valve cover, or a bad gasket.
Show original supplier description
The RB N54 PCV Valve offers an upgraded replacement for the factory PCV valve in your N54 Engine, specifically recommended for high-performance applications or those with higher mileage. The stock plastic PCV valve is known to not hold pressure effectively, even when new. This can lead to the leakage of turbocharged pressures into the crankcase during boosted conditions. Further issues like crankcase pressurization or oil loss can also stem from a cracked valve cover, loose valve cover, or a faulty valve cover gasket. This upgraded valve addresses the limitations of the OEM component by providing a more robust seal. It's important to note that this solution specifically targets the PCV valve itself and does not rectify issues with a leaky valve cover gasket, which is a common problem on the N54. While the RB PCV Valve does not negate the benefits of using an oil catch can, it may reduce the amount of oil collected. The product utilizes genuine OEM core PCV valves to ensure the highest performance and quality available. Please be aware that the RB Screw-on Cap is not included with this PCV valve and must be ordered separately. The pictured cap is solely for illustrating how the RB PCV Valve interfaces with the cap.
