Doing some light maintenance on an Airbus A320 series.
Oil filters - 1 on pressure side and 1 on return side. Each has its own bypass indicator with a red dot near the top. They are steel mesh, few hundred dollars each. You can also see the 4 chip detectors here, located below the oil filters, also containing red dots.
Top off looks good.
Don't forget those cabin air filters! They are like 2 feet in diameter.
Check the avionics wiring.
