When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system  baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain system comes complete with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

Features:

  • 6061-T6 billet machined body, anodized black for lasting protection and appearance
  • Strategically positioned 4 chamber baffle system maximizes oil / air separation 
  • Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
  • Sealed with a pre-installed viton O-Ring
  • Includes 2.5mm allen key to remove baffle plates for cleaning
  • Engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can
  • Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
  • Optional use drain hole - drain kit included!
  • Universal mounting kit

This hose directs the oil & combustion vapors from the valve cover and directs them to the intake manifold where they are put through combustion again in order to reduce emissions. When installing one of our N54 Oil Catch Cans the connections on this hose will often break. We recommend replacing this hose at the same time as your catch can. When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

Part#: VTT-N54-PCV

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 oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. Bosch's Oxygen sensors are high quality and will give you the the longest and best performance for the price.

N54 powered BMW vehicles have two of these tanks, one for each turbo. They accumulate and hold vacuum/air to be used on both turbos. The factory plastic N54 boost vacuum tanks tend to leak and cause problems. If vacuum can't be stored the wastegates will not function, leading to common low boost or overboost faults. We have the solution, the all-new heavy-duty BMS tanks. Specifically made for stock to high-boost N54 engines. Each tank is made from 100% aluminum and features two CNC machined aluminum end caps and are anodized black to complement your engine compartment. Featuring BMS logos, metal barbed vacuum fittings, and integrated brackets for solid mounting in the factory location. Not only do these look awesome under the hood, but they will also last forever.
