Abstract

The invention relates to a cylinder head gasket made of metallic material for internal combustion engines with components flanged laterally on to the engine block, which can reliably seal over a lengthy period of time even critical seal gaps in the region of additional components flanged on to the engine block. For this purpose, in the region of the gap between the engine block and/or cylinder head and the flanged-on component(s) there is in the cylinder head gasket at least one opening which communicates with at least one reservoir containing a plastic sealant mass.
