The oil pump circulates engine oil under pressure to the rotating bearings, sliding pistons, and camshaft, ensuring proper lubrication and cooling of these components.

Signs include low oil pressure readings, increased engine temperature, unusual engine noises like ticking or whining, and the illumination of the oil pressure warning light.

Yes, a malfunctioning oil pump can lead to insufficient lubrication, resulting in increased friction, overheating, and severe engine damage if not addressed promptly.

While oil pumps are designed for long-term durability, it's essential to follow the manufacturer's maintenance schedule and address any oil pressure issues immediately to prevent potential failures.
