An intermediate deck (4) is situated between the flame deck (2) and the oil deck (3), and at least one injector pipe (5) extends from the flame deck (2) up to the oil deck (3).

After evaporation of the solvent, the solid substance remains on the component and acts as an oil barrier.

A method and device for the application of an oil barrier (C) on a component (5) of a bearing system.

Oil barriers of this type can be easily provided on the rotor part and stator part by means of dipping.

The invention relates to a cylinder head (1) of an at least one-cylinder internal combustion engine with direction injection of a motor vehicle with a flame deck (2) and with an oil deck (3).

Surface areas of said parts are provided with a so-called oil barrier in order to prevent the oil from creeping from the bearing system to the environment.

According to the present invention, said oil barrier comprises a monolayer of perfluorocarboxylic acid anions, especially those having a chain length of 10-20 C-atoms and/or perfluoroalkylthiol anions.
