The crankcase vent system separates liquid oil from the air inside the engine and intake. When working correctly, oil is removed from the intake air and returned to the oil pan. Oil vapor remains and is burned up in the combustion chamber. Every car has some form of crankcase ventilation, also known as a PCV, CCV, oil separator, and a cyclonic separator. PCV system are notoriously failure prone, leading to high oil consumption, burning oil, loss of power, misfiring, and high carbon deposits. Signs of a failing PCV include: whistling noises in the intake, blueish smoke in the exhaust, high oil consumption, and thick white or yellow gunk under the oil cap. When it happens on your BMW cars, you can take this PCV Hose Kit for direct replacement. Fits for the Following Vehicles: for 2001-2005 BMW 320i, 2000 BMW 323Ci, 2000 BMW 323i, 2001-2002 BMW 325Ci, 2003-2005 BMW 325Ci M54, 2006 BMW 325Ci, 2001-2002 BMW 325i, 2003-2005 BMW 325i M54, 2000 BMW 328Ci, 2000 BMW 328i, 2001-2006 BMW 330Ci, 2001-2005 BMW 330i, 2001-2005 BMW 330xi 325xi, 2001-2005 BMW 525i, 2000 BMW 528i, 2001-2005 BMW 530i, 2004-2006 BMW X3, 2000 BMW Z3 2.8 L6, 2000-2002 BMW Z3 2.5 L6, 2001-2002 BMW Z3 3.0 L6, 2003-2005 BMW Z4. Customers can find the product you need accurately according to the OE number. OE part number: Crankcase Pressure Regulator Valve 11617501566, Upper Oil Separator Vent Tube 11617504535, Crankcase Vent Return Pipe 11617504536, Oil separator to valve cover 11611432559, Oil separator to dipstick tube 11157532649. BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. Crankcase breather valve is used to purge oil vapor from engine block into valve cover. However, sometimes condensation can cause it to freeze, causing entire oil separator system to fail, crack, and disintegrate. Replace all components of oil separator system together to prevent damage to all aspects of engine.

Trial assembly to ensure proper connection

When I animated it I thought it was too small until I compared it I tried it on and at first I thought it was a bit larger but realized it the more I pressed it Also it fits very snugly and My car works perfectly. Installation isn't easy, but go to YouTube and search "50s Kid". Who has two options for attaching them, I went the route of removing the air intake to replace additional parts.

Pros
  • The crankcase ventilation system separates liquid oil from the air in the engine and intake. In proper operation, oil is removed from the intake air and returned to the oil pan. Oil vapors remain and burn in the combustion chamber. Every vehicle has some type of crankcase ventilation, also known as a PCV, CCV, oil separator and cyclone separator.
Cons
  • Could have chosen a newer model

Some parts don't fit together easily

I installed this on my son's 2001 325i because the hose to the dipstick had a vacuum leak. Two hoses did not close. Once I was able to get it to stay in place by squeezing the tabs after squeezing the hose (very hard to do). The other one I had to use with zip ties because it didn't hold up at all. It works but I would recommend just buying the OEM part. You'll probably only need one hose anyway, and that's probably the one that connects to the dipstick. If so, then just buy an OEM hose. So…

Pros
  • The PCV system is notorious for being prone to failure, resulting in high oil consumption, oil combustion, loss of power, misfire and high carbon buildup. Signs of a PCV failure include: whistling noise in the intake, bluish smoke in the exhaust, high oil consumption, and thick white or yellow dirt under the oil cap. If this happens to your BMW vehicles, you can use this PCV hose kit as a direct replacement.

If you are not a mechanic, do not buy this kit.

strips are not quite at the same angle as the original. So you will have trouble making some snap connections. If the hoses were 6mm longer, there would likely be these issues. This is especially noticeable in the foam-lined tube that runs through the top of the manifold. You'll likely end up removing the cleaning foam. For me I had to cut off one of the ends and connect a piece of vacuum hose with zip ties. For me the kit was worth it because I know how to see those little issues and find a…

Pros
