An oil fill cap for an internal combustion engine replaces a standard cap and provides separation of air and oil in a separation zone within the cap body. The cap body defines a plurality of passages therethrough, including an upstream passage, and first and second downstream passages meeting at a separation junction. The cap body defines a separation zone at the separation junction and receiving the air/oil mixture from the engine through the upstream passage, and sending separated air to the first downstream passage, and sending separated oil to the second downstream passage.
