Aircraft; Procedure
Had a Low Oil Pressure indication; followed by a suspected fume event. Returned to departure airport. Landed overweight and did not declare an emergency. Cause: did not have time to refer to FOM. QRH did not contain required declaration guidance in the overweight landing procedure. Suggestions: there is a full page of 'additional information' attached to the Overweight Landing Procedure in the 757 QRH. It would be helpful to add a reminder that; at [company]; per FOM; a declaration of emergency with ATC is required for all overweight landings. It would have also been great if the Dispatcher had the procedure/authority to declare for the flight as we were able to communicate we were returning and were overweight.
Right Engine oil pressure at 33 psi (yellow band) after takeoff; followed by increased fumes in cockpit and cabin. Returned to ZZZ and although told ATC we were returning due to fumes and were going to land overweight. We did not specifically declare an emergency as required by Flight Manual part 1.
B757 flight crew reported experiencing a low oil pressure indication followed by fumes in the cockpit. Flight crew decided to return to the departure airport and executed an undeclared overweight landing.
