Abstract
In a ventilating arrangement for an internal combustion engine, a venting line for supplying venting gases from the engine crankcase to the air intake pipe includes an oil separator from which an oil return line extends downwardly on the outside of the engine crankcase front wall into an upwardly open oil pocket also arranged on the outside of the crankcase front wall so as to form a siphon therewith through which the oil can return from the oil separator to the oil sump in the oil pan under the crankcase against the excess pressure normally developing therein during engine operation.
