A cylinder head cover having a bearing device that includes at least two bearing blocks for supporting a camshaft, and one connecting element. The bearing blocks are axially penetrated in a first through-opening by the camshaft and are fixed in an aligned position with respect to one another by the connecting element. The bearing blocks, the connecting element and the camshaft form a prefabricated assembly. The cylinder head cover is connected via at least one additional connecting element with the bearing device, whereby a unit consisting of the cylinder head cover and the bearing device are mounted on the cylinder head.

Cylinder head cover

The invention relates to a cylinder head () of an internal combustion engine, comprising at least one hollow camshaft () which forms an exhaust for blow-by gases containing oil mist from the crank housing and is also embodied as an oil mist pre fractionator for the preliminary separation of the oil part from these gases. Furthermore, an oil mist post-fractionator () is axially arranged on the end of the camshaft (), in order to carry out an especially effective separation of oil dissolved in the blow-by gases.
