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
  • 11157567801, 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

    It's no secret that B58 BMW turbo motors can suffer from oil control problems, causing the oil to blow through and coat the intercooler and charge piping, gunking up intake valves and the VANOS system, lowering the effective octane, and generally degrading engine performance. The higher your boost levels and the higher the mileage, the more apparent these problems become. The solution to this problem has finally arrived. The Burger Motorsports oil catch can. While there are other catch cans on the market, they all fall short in various areas. Some are mounted on the hot/turbo side of the motor, preventing proper vapor condensation. Others utilize hoses that are too small and runs that are too long to allow proper PCV ventilation, causing internal motor/ring sealing issues. Some have insufficient or no internal baffle systems, while others have internal baffle systems that are too restrictive. Some even bypass the PCV system altogether, venting crankcase gas and odor to the atmosphere. Most are simply repackaged oil catch cans from smaller/lower power motors shoehorned into place in the turbo BMW engine bay. To solve these problems, Burger Motorsports designed their oil catch can kit from the ground up specifically for the 2025 and newer Gen 3 B58 turbo BMW application. It features 100% CNC machining with zero welding for a precision fit and long life. The can itself is guaranteed for the life of the vehicle. The hoses exceed the OEM PCV piping in diameter, and that flow rate is maintained throughout the entire oil catch can, ensuring no excessive crankcase pressure buildup. The BMS OCC retains the factory fully closed loop PCV operation, preventing any PCV vapor from leaking to the atmosphere. The mounting locations are selected to minimize the line length, allow more efficient operation, and retain a stealth look. Installation takes around 20 minutes, includes all required hardware, and is 100% reversible. Simply unscrew the base of the can or use the drain plug to safely dispose of captured oil with the rest of your used motor oil during oil changes.

    If you’re dealing with emissions-related faults, the Secondary Air Injection (SAI) pump is an important component to check. This system is designed to inject fresh air into the exhaust manifold during cold starts, helping reduce harmful emissions while the catalytic converters warm up. When the SAI pump is damaged or not operating correctly, emissions can increase and fault codes may be triggered. In states that require emissions testing, a failed air pump can easily result in a failed inspection. Replacing a faulty Secondary Air Injection Pump helps restore proper emissions control, clear related fault codes, and ensure your vehicle remains compliant with emissions requirements.

    The Pressure Control Ventilation (PCV) valve is designed to route high-pressure blow-by gases from the crankcase into the intake manifold, relieving excess pressure while recycling gases back into the combustion process. When the PCV valve fails, it can lead to excessive oil consumption, rough idle, and stored engine fault codes. Replacing a worn or faulty valve restores proper crankcase ventilation, smooths out idle, clears codes, and helps keep your engine performing at its best.
