Oil Separation & Breather System for BMW 3 Series E90 (2006-2011)

Clear BMW chassis

Please ensure your correct model is selected

Every car has a crankcase vent system that is supposed to suppress oil from making it into the intake ports and combustion chamber. A good functioning system will separate oil from the atmosphere and return it to the oil pan (or collect it in a catch can) while allowing the leftover vapors to burn in the combustion chamber or recirculate through the system. This has always been known as a PCV system (Positive Crankcase Ventilation) but BMW has several other names for it - oil separator, crankcase vent (CCV), and cyclonic separator. Failures in the system will allow raw oil to enter the intake and eventually into the engine itself which can have disastrous effects on engine performance and longevity. As emissions regulations on oil and gas venting have gotten more stringent the PCV systems have gotten more complex and failure prone. And because the CCV is intertwined with other systems you could experience rough running, loss of power, higher oil consumption, misfiring, stalling, or other annoying issues. There is no replacement interval for these so we recommend inspecting your crankcase vent system as part of your regular maintenance routines. Symptoms of a bad crankcase vent are: whitish or yellowish film on the underside of the oil cap, whistling/squealing noises (not caused by a belt), suction on the oil cap that makes it hard to unscrew, large amounts of white smoke from the exhaust, and excessive oil consumption.

The PCV system removes engine blow-by gases and flushes the crankcase with fresh air. PCV system problems result in numerous and sometimes severe problems including multiple oil leaks, contamination of multiple sensors and catalytic converters, deposit build-up in the air intake passages, and failed emissions tests.

The crankcase oil vent system on the N52/N54 is one of its weakest and cheaply designed systems. We see crankcase vent issues on even stock engines but with more boost the problems are exponential. This Vargas upgraded PCV valve, and an oil catch can, are what the N54 engine needs and may alleviate most of your oil and boost leak issues. The PCV valve is supposed to let oil either return to the oil pan or pass through the intake manifold and get burned up in the combustion chamber. However, BMW used a weak plastic vent valve that doesn't seal well when under boost. Instead of  closing and venting the oil out of the intake, it's forced through this valve and into the intake and coating your valves with oil residue and carbon. Most boost equals more oil forcing its way by. This upgraded N54 PCV valve uses higher grade materials, including aluminum, to provide a better seal and prevent oil from entering the intake. It's an easy install and a must-have item when considering any turbo work.

The OEM plastic Positive Crankcase Ventilation (PCV) valve does not hold pressure well, even when brand new. This means that when you are in boost conditions, the highly pressurized PCV valve leaks charged air back into the crankcase. Depending on the condition of your PCV valve, this can range from irritating to dangerous. Additionally, if your valve cover is cracked, loose, or has a bad gasket, you are likely experiencing a pressure leak either internally or externally, as well as potential oil loss issues. ECS Tuning now offers a solid aluminum PCV valve upgrade designed to address these issues by preventing leaks and outlasting the standard BMW-designed PCV! The internal components of this aluminum PCV valve fit tighter than the OE design and can withstand significantly more abuse, perfect for high mileage N54s, N54s that have been tuned, or N54s with upgraded turbos (larger twin or big single turbo builds). This may not be your last PCV Valve, but it will certainly outlast both the Genuine BMW and other common aftermarket alternatives!

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or solid oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create a oil sludge condition that is impossible to clear. Thankfully, the CCV is replaceable on the early N52 engines (2006) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

The OEM BMW plastic PCV valve can struggle to maintain pressure, even when brand new. A leaky PCV valve allows turbocharged pressures to escape into the crankcase, especially during boosted conditions. The extent of the leak depends on the PCV valve's condition, and additional issues like a cracked or loose valve cover or a faulty gasket can compound the problem, leading to oil loss and excessive crankcase pressure.

  • Solves issues with the OEM BMW plastic PCV valve
  • Helps prevent turbocharged pressure leaks into the crankcase
  • Doesn't address valve cover gasket problems
  • Suggested gasket replacement when removing the valve cover
  • Genuine OEM core PCV Valves for top performance and quality

The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create an oil sludge condition that is impossible to clear. The plastic hoses can become brittle and crack which leads to vacuum leaks and oil leaks. Thankfully, the CCV is replaceable on the early N52 engines (2006 and some 2007 models) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

This is a kit containing the oil separator, the vent hoses, and the intake manifold gaskets that are done during a typical oil separator replacement. Complete kit includes:
  • 11617531423, Genuine BMW oil separator
  • 11617559530, vent hose
  • 11157522931, oil separator hose
  • 11157567802, return hose
  • 11157537701, extraction hose
  • 11617547242, intake manifold gaskets (set of 6)
    The intake manifold must be removed to access the oil separator so new profile gaskets are included. We also recommend (but not required) a new oil separator fitting on the intake manifold because it's one of the heated elements that vaporizes the oil as it enters the intake.

    The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

    This kit fits the following BMWs:
    10/2005+ E90 BMW 325xi 330xi - Sedan
    10/2005+ E91 BMW 325xi - Wagon

    The OEM plastic PCV valve does not hold pressure well even when brand new. What this means is that when the turbochargers are making boost, pressurized air can become forced backwards through the valve and back into the crankcase. Depending on the condition of your PCV valve this can range from irritating to dangerous as a pressurized case can cause all sorts of issues. Additionally, if your valve cover is cracked due to age or has a bad gasket you are more than likely experiencing a pressure leak either internally or externally. These two features can cause even a low-mileage N54 to run like a tired elephant, sometimes even unlocking a special bonus function known as "Limp Mode". The solution is to replace any failed components and upgrade the PCV valve to something more capable withstanding the abuse of a turbocharged environment. FTP Motorsport has you covered with this solid aluminum valve assembly. It is essentially the same thing that came in your car from the factory, made out of aluminum. The internal components have also been made to fit tighter and outlast the life of an off the shelf replacement. No, this won't be the very last PCV valve you buy, but it will most certainly alleviate a lot of headaches common to N54 owners. And if you're tuned, big twin or single swapped you need one of these yesterday.
