RB N54 PCV Valve Upgraded Replacement

Availability: In stock

The RB N54 PCV Valve is an upgraded replacement PCV valve for your N54 Engine and is strongly recommended for your high performance (or higher mileage) N54.

The OEM plastic PCV valve does not hold pressure well even when brand new. What the leaky PCV valve means is that when you are in boosted conditions, the "highly" pressurized PCV valve leaks turbocharged pressures into the crankcase. Pending on the condition of your PCV valve it could leak worse than others. Also if for some reason your valve cover is cracked, loose, or has a bad gasket; you also could develop a pressure leak either external to the engine or internal into the crankcase causing further pressurization of the crankcase or other oil loss issues.


  • The solution will only fix the OEM PCV valve itself and not a leaky valve cover gasket, which is also a very common problem on the N54 Engine. We do recommend if EVER pulling off the valve cover to always replace the OEM gasket with a new one and use a light amount of high quality sealant around these pressurization ports that are fed through each intake port.
  • The RB PCV Valve solution will not negate the Pro's of Oil Catch Cans, but could reduce what they otherwise collect. It also could be reasoned that those who catch a TON of oil have a less "healthy" internal valve cover PCV valve or PCV systems, or alternatively engines that produce excess blowby.
  • The RB PCV Valve does not come with the RB Screw-on Cap as pictured. The picture is simply to illustrate how the RB PCV Valve interfaces with the RB PCV Screw-On Cap. You will need to order the RB PCV Screw-On Cap as a separate item in order to receive it.
  • The RB PCV uses only Genuine OEM core PCV Valves offering the absolute best performance and quality. There are none available (nor will there ever be) that beat the performance of this valve.
