RB BMW N54 PCV Valve (135i & 335i)
Rob Beck Replacement PCV Valve
Available for N54 twin turbo
You may also wish to upgrade the BMW N54 Rob Beck PCV Valve Screw-on Cap.
Replace your worn out original valve with this direct replacement to eliminate a potential boost leak in higher horsepower applications.It 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" pressurised 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 pressurisation 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 pressurisation 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 uses only Genuine OEM core PCV Valves offering the absolute best performance and quality.
