How can you tell if oil pump is clogged?

You can tell if an oil pump is clogged by observing signs such as low oil pressure readings on the gauge, unusual engine noises due to insufficient lubrication, or warning lights on the dashboard indicating oil pressure issues. Additionally, if the oil appears dirty, thick, or contains debris, it may indicate a clog. A thorough inspection of the oil filter and lines can also reveal blockages. If you suspect a clog, it's advisable to have a professional mechanic evaluate the system.
