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. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

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.

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.

R55-R59 Oil Catch Can Kit for N18 MINI Engines

Introducing the newly updated R55 through R59 Oil Catch Can kit for MINIs equipped with the N16 or N18 engine. This kit includes a "designed-to-fit" stainless steel bracket, mounting hardware, and pre-assembled hoses for easy installation—no drilling or special tools needed. Note: This kit has been redesigned to fit directly behind the outlet of the airbox on the firewall, using the factory tab located on the firewall.

Despite skepticism from "forum experts and social hysteria," an Oil Catch Can (OCC) is essential. Many MINI owners suffer from carbon buildup on their intake valve due to oil being recycled through the intake tract. With the M7 Oil Catch Can, your MINI Cooper's engine will be protected from excessive oil and hydrocarbon buildup, preventing performance-hindering oil film and sludge. Direct injection in 2007 & up MINIs exacerbates the issue, leading to oil blow-by burning onto intake valves, resulting in power loss and expensive repairs.

By capturing excess oil vapor and particles, the M7 Oil Catch Can ensures optimal engine performance. 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
  • Eliminates intake tract oil contamination and intake valve damage
  • Prevents premature sensor failure
  • Maintains engine performance at peak levels
  • Carbon Fiber canister with billet bright aluminum top and bottom

The M7 Oil Catch Can is not only functional but also a work of automotive performance ART! It features a 100% carbon fiber housing with CNC machined billet aluminum top and bottom, adding a sharp look to your engine compartment.

All hoses, brackets, clamps, necessary fittings, and easy-to-follow detailed step-by-step instructions are included, along with an oil drain plug and an easy-to-view sight tube. The sight tube allows you to monitor the oil level in the can. The hoses are high-quality "Made in the USA" automotive grade, designed to withstand the rigors of the under-hood environment without degradation.

The secondary air injection pump injects fresh air into the exhaust stream to help burn off harmful pollutants in the catalytic converter. If the injection pump begins to fail, since it is a vital part of the emissions system, a fault code will be triggered. Sometimes, when pulling off the lower secondary air pipe, you may see water pour out. This is a sign that your pump is more than likely faulty. By simply replacing this pump, efficiency can be restored and there will be no worry about failing an emissions test.

M7 Oil Catch Can Kit for MINIs

Newly Updated Kit for Improved Engine Performance

The newly updated R55 through R59 Oil Catch Can kit for MINIs equipped with the N16 or N18 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.

Why You Need an Oil Catch Can

"Forum experts and social hysteria" may say an OCC is not needed, but we beg to differ. Many MINI owners suffer from carbon buildup on their intake valve due to 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.

This oil film & sludge can appear in other critical places throughout the engine, such as the intercooler and the MAF sensor (Mass Air Flow), where clean surfaces are critical for maximized heat transfer and engine performance.

Features and Benefits

  • Prevents intake tract oil contamination and intake valve damage
  • Prevents premature sensor failure
  • Keeps engine performance at peak levels
  • Increases flow area by 77% for improved oil separation
  • Includes billet aluminum oil catch can with coalescing oil separation technology and integrated dipstick
  • Comes with two molded oil-resistant silicone hoses with STS technology (available in Red or Black)
  • Includes installation hardware kit and printed instructions
  • 100% carbon fiber housing with CNC machined billet aluminum top and bottom

Easy Installation

With our exclusive "Exact-Fit" pre-assembled hose kit and brackets, installation is super-easy. All hoses, brackets, clamps, necessary fittings, and easy-to-follow detailed step-by-step instructions are included. An oil drain plug and an easy-to-view sight tube are also provided, allowing you to monitor the oil level in the can.

Beware of other "low-cost" catch can systems that use silicone hoses, as oil and silicone are not compatible and silicone hoses will eventually deteriorate, causing a mess in your engine compartment.

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. This oxygen sensor for BMW's with the N52, N54, and N55 3.0L engines. This 490mm bank 2 oxygen sensor is mounted after the catalytic converter.
