The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition.

The factory hoses offered through BMW are plastic and will yield the same results of becoming brittle and damaged over time. Our solution is a premium replacement that will outlast everyone of the OEM replacements. Our Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to ensure your S54 is free from vacuum leaks and performing properly.

CSL Vent Hose (11157833649) - Silicone Crankcase Vent hose is a direct replacement

Key benefits:

Lifetime replacement of the brittle OEM plastic crankcase breather hose that is susceptible to cracking overtime from constant heat cycling

Design:

Retains OEM hose end fittings to ensure proper seal

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

The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition. Replace the brittle or broken line that attaches between the oil separator and air box. Our Turner Silicone Crankcase Hose can be used in place of both the standard and CSL intake boxes.

Our engineers at Turner sought out to solve the degrading issues that happens with the factory crankcase vent hose and found the best solution is a silicone replacement. Our Turner Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to prevent vacuum leaks and lackluster performance. Simply take your factory crankcase vent hose and remove the ends; the factory ends can be installed on the new Silicone Vent Hose with the supplied clamps for a tight seal.

Part#: VTT-N54-PCV
In Stock

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.

Upgrade your MINI with the M7 Oil Catch Can Kit__xxSTARTxx__/h1

The newly updated R55 through R57 Oil Catch Can kit for MINIs equipped with the N14 engine comes with a "designed-to-fit" stainless steel bracket, mounting hardware and pre-assembled hoses. Installation is super easy...no drilling and no special tools are needed. NOTE: This kit has been redesigned to fit on the firewall directly behind the outlet of the airbox. It uses the factory tab located on the firewall."Forum experts and social hysteria" say an OCC is not needed but we beg to differ. Why do so many MINI owners suffer from carbon buildup on their intake valve? The answer is oil being recycled through the intake tract to be burned. With the M7 Oil Catch Can, your MINI Cooper's engine will be protected from excessive oil and hydrocarbon buildup which leads to performance-hindering oil film and sludge along your intake tract, on your engine control sensors and on your engine's intake valves. Because the 2007 & up MINI is direct injection the intake valves do not benefit from the cleaning action provided by the gasoline as in older port injection engines. Now all the oil blow-by burns onto the intake valves and builds up into a flow choking hydrocarbon mess. The end result is loss of power and a very expensive repair bill. This oil film & sludge can appear in other critical places throughout the engine-- such as the intercooler-- where clean surfaces are critical for maximized heat transfer and on your MAF sensor (Mass Air Flow) where the film will cause the sensor to send a false signal to your ECU killing performance.

By capturing excess oil vapor and particles, the M7 Oil Catch Can ensures that oil film and sludge will not become a factor in your vehicle's performance. If you don't think your engine is pumping oil back through your intake system, remove the breather tube and look at all the oil!. The breather tube connects directly to you intake hose and directs this oily mess back through your engine to be burned.

Now with our exclusive "Exact-Fit" pre-assembled hose kit and brackets installation is super-easy.

Features:

  • Pre-assembled hose assemblies.
  • Stainless steel bracket and mounting hardware
  • Eliminate intake tract oil contamination and intake valve damage.
  • Prevent pre-mature sensor failure
  • Keep engine performance at peak levels
  • Billet Aluminum Construction
  • Bright Black Anodized Finish
  • Laser Etched M7 Logo

The M7 Oil Catch Can is not only functional is a work of automotive performance ART! It is CNC machined from billet aluminum and adds a sharp look to your engine compartment.

All hoses, brackets, clamps, necessary fittings and easy to follow detailed step-by-step instructions are available on this page in .PDF format. The design includes an oil drain plug and an easy to view sight tube which indicated the oil level within the can. The hoses are high quality "Made in the USA" automotive grade designed to withstand the rigors of the under-hood environment and to not degrade when exposed to oil. Beware of other "low cost" catch can systems that use silicone hoses because oil and silicone are not compatible. Silicone hoses will will eventually deteriorate and make an absolute mess of your engine compartment.
