Abstract
Abstract A venting arrangement with integrated oil separator is arranged at a crankcase of an internal combustionengine with preferably V-shaped cylinder rows and includes a housing with the oil separator. The housing is formed for reasons of structural simplification by an upper part and by a lower part which have both pot-shaped configurationand upright, mutually overlapping boundary walls and form a unit. The boundary walls of the upper part are supported at the crankcase by means of flanges which assures a simple installation of the venting arrangement.
