The Lubricating Oil Pump is a crucial component of engine. It is responsible for pumping oil throughout the engine to ensure that all moving parts are properly lubricated and protected against wear and tear. The pump operates by drawing oil from the oil pan and pushing it through the engine's oil passages, including the crankshaft, camshaft, and valve lifters. This ensures that all critical components receive adequate lubrication, which is essential for proper engine function and longevity.
