If we talk in more detail about the crankcase, it means a fairly dense body part of the power plant, inside which the crankshaft is located. There are cylinders in the upper part of this device. Of course, depending on the make and model of the vehicle, the internal components of the crankcase can be very different. It should be noted, however, that the crankcase ventilation pipe is considered one unchanged component.

The principle of the FEBI BILSTEIN brand Hose, crankcase breather

In fact, these elements are designed to perform a specific function. In particular, this concerns the formation of a connecting mechanism for the pipeline. In the absence of branch pipes, it is difficult to imagine a full-fledged ventilation system of the motor. Of course, over time, the crankcase ventilation branch pipe becomes unusable, as a result of which it becomes necessary to replace it. However, in order for the new device to perfectly cope with all the assigned functions, it must be selected correctly.
