Abstract

In an internal combustion engine with a motor block (6) and a longitudinal extending anti-rotation guide (5), which includes receiving recesses situated at apportioned spatial distances, one from the other to receive valve tappets and is affixed in a receiving groove of the motor block (6). The guide (5) is constructed as an injection molded component with a one-piece, molded-on, elastically expanded or deformable clip, which engages in a complementary receiving contour on the motor block (6).
