Aircraft
Normal brief with the complex single engine departure procedure completed. Takeoff was normal with no complications. Climbing out at about 10;000 feet; we started to smell something and noticed the oil pressure on the left engine was falling. Then the oil temperature started rising. Captain gave the FO (first Officer) the airplane; so he could get into the checklist. FO took the controls; Captain radioed for a level off altitude. The oil temperature turned red and the oil pressure was very low; as well; no oil pressure light. FO pulled the engine back towards idle to try to get the oil temperature to lower. Captain started in on the Oil Temperature Checklist. FO leveled off at 12;000 feet and slowed to 250 knots. Captain requested a turn back to [the departure airport] to land. ATC began giving us vectors and lower altitudes. The oil temperature began a nice decrease. With the oil temperature back in the normal range; the oil pressure began rising; as well. We returned for the ILS approach with delay vectors to complete the checklist; brief; and landing data. On the approach the oil pressure and oil temperature was parallel to the good engine. A normal approach; landing and taxi in with shut down checklist was completed. As a crew; we worked seamlessly well together! The Captain did a superb job.
B757-200 First Officer reported a drop in oil pressure and a rise in oil temperature in the left engine during climb and returning to departure field.
