It is a gear-type pump driven by the engine's camshaft or accessory drive to circulate oil throughout the engine, ensuring vital components like bearings, pistons, and the turbocharger are properly lubricated and cooled. Over time, wear can reduce oil pressure, leading to engine damage; mechanics typically replace this pump during a major engine overhaul or when diagnosing low oil pressure issues.
