How does a clogged oil pump pickup screen affect an engine?

• A. Increases oil pressure
• B. Decreases oil pressure
• C. Has no significant effect
• D. Only affects oil temperature

Answer: (B)

A clogged oil pump pickup screen impedes the flow of oil into the pump, which is critical for maintaining proper lubrication throughout the engine. As the screen becomes obstructed by sludge, debris, or contamination, the oil pump struggles to draw in sufficient oil from the oil pan. This restriction causes a decrease in the volume of oil available to be pumped through the engine, leading to lower oil pressure. Oil pressure is essential for ensuring that all moving parts receive adequate lubrication to prevent friction and wear. When the pressure drops, it can result in insufficient lubrication, which may lead to increased wear, overheating, and potential engine damage. Therefore, a clogged oil pump pickup screen directly correlates to decreased oil pressure, which adversely affects engine performance and longevity.
