When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

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 plastic hoses and oil separator can crack or become faulty, leading to vacuum leaks or oil leaks. This is caused by the stress the plastic components are exposed to during heating and cooling cycles, especially if the vehicle is not brought up to operating temperature during driving in cold weather climates.

This kit includes the needed hoses, oil separator, mounting grommet, and hardware.

Fits the following BMWs:
2000-2003 E39 BMW 530i

M7 Oil Catch Can Kit for MINIs

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 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
