An arrangement for protecting ignition means in an internal combustion engine includes a cylinder head and two longitudinal parallel valve cover banks mounted thereon. Between the valve cover banks there is a longitudinal space for ignition means to the respective combustion chambers of the engine. Such a space and ignition means with their connections located therein are usually subjected to dirt, which reduces the functional reliability of the engine. To eliminate this and to facilitate engine service, the space is formed as a trough with a bottom and two end walls in the cylinder head, the trough being covered by a lid joining on to the valve cover banks and to at least one of its end walls and having at least one opening for ventilation and drainage.
