Abstract

The present disclosure relates to an internal combustion engine for a motor vehicle. The internal combustion engine has a cylinder head, a crankcase and a cylinder head gasket. The cylinder head, the cylinder head gasket and the crankcase form a sealing region for sealing at least one combustion chamber. A first recess is arranged within the sealing region and at a distance from the at least one combustion chamber. A first leakage gas passage extends from the first recess to a first surface exposed to the environment of the internal combustion engine or to a ventilation passage of the internal combustion engine.
