There are several signs of a failing oil pump. A few signs are low oil pressure, increased temperature, and noise.
No oil pressure.
You'd be lucky if you can hear it, unless something in the pump is severely loose and rattling around in there. Signs of a bad oil pump can be numerous however. Overheating, loss of power, grinding, oil in the intake, strong random vibration....
No, if you have oil in your oil pan, you have other problems. It has nothing to do with your water pump going out or being bad.
The oil pump rattling is very unlikely, a bad pump causing other components to rattle and damage themselves is VERYlikely.

Loss of oil pressure.
To determine if the oil pump on a 1991 Ford F-150 is bad, check for low oil pressure on the gauge or warning light activation. Listen for unusual noises, such as knocking or tapping sounds from the engine, which could indicate insufficient oil circulation. Additionally, inspect the oil for signs of contamination or metal shavings and ensure that the oil level is adequate. If these symptoms are present, consider testing the oil pressure with a mechanical gauge to confirm the pump's functionality.
