Angry Ass | S38B36 Crank Case Ventilation Maintenance Kit

ATTENTION: Hose 11611312670 is currently back ordered from BMW. Hoses are expected in late July. We are working on an alternative with SAMCO. In the meantime, if you would like to order a kit, it will ship without this hose, and once it is available we will ship it out to you.

Unfortunately, the vent line from the valve cover to the oil separator for the S38B36 is no longer available, which makes this maintenance kit a bit more complicated for us. We decided to use the line from the S38B38, which is still available and a mostly direct fit, with the exception of interference with the S38B36 vacuum reservoir. Our fix for that is a custom 6061 aluminum vacuum reservoir.

We’ve reduced the length of the reservoir to allow the S38B38 vent line to clear, and increased the diameter of the reservoir to maintain the same capacity as OEM. Up to you if you’d like new Norma stainless steel hose clamps to go with your new OEM BMW hoses; and, if you want to take things a step further, replace the rubber isolators and oil separator o-ring located on the bottom of the plenum.
