ABSTRACT:
An internal-combustion engine has a cylinder block and crankcase and a case structure which preferably has two cylinders or cylinder bank rows arranged in a V-shape with respect to one another. An endless drive extends on the face of the cylinders or cylinder bank rows, which drive comprises a timing chain for connecting a crankshaft with camshafts arranged in the cylinder heads. The timing drive chain is covered by a timing drive cover. The timing drive cover, or the case is structure situated opposite the timing drive, cover has a ribbing by which a targeted separation and/or return takes place of the oil carried along by the timing chain in the direction of the cylinder heads. As a result, among others, the venting of the crankcase is not hindered, which takes place by way of the timing chain case.
