Cracks and swelling in old hoses can result in oil and vacuum leaks, compromising engine performance.

  • Essential component for BMW engine functionality
  • Prevents clogging and potential hose failure
  • Minimizes oil and vacuum leaks
  • Convenient replacement when replacing crankcase vent valve

Upgrade your BMW N55 engine with our Silicone Crank Case Vent Hose, a premium replacement for the fragile, failure-prone factory hose. Over time, the stock plastic hose deteriorates due to constant exposure to heat and oil, leading to cracks and leaks. Our solution? A high-quality silicone hose engineered for superior durability and long-term reliability.

To further enhance performance, we’ve lined the hose with fluorosilicone, providing exceptional resistance to oil and chemical degradation. Designed in-house using advanced CAD modeling and 3D scanning, this hose offers a precise OEM fit while eliminating the common weaknesses of plastic construction.

Each kit includes stainless steel hose clamps for a secure, hassle-free installation. Whether you’re replacing a worn-out CCV hose or upgrading for added peace of mind, this premium solution ensures your BMW N55 runs smoothly and efficiently for years to come.

Features:

Direct OEM Fit – Retains factory hose dimensions while eliminating reliability issues.
High-Performance Silicone – Resists heat-related wear for long-lasting durability.
4-Ply Fluorosilicone Lining – Superior protection against oil and chemical exposure.
Stainless Steel Clamps Included – Secure installation and extended service life.

The rubber hoses and oil separator can crack or become faulty, leading to vacuum leaks or oil leaks. This is caused by the stress the 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, and hardware.

Fits the following BMWs:
1999-2006 E53 BMW with M62 4.4L 4.6L

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
