Seals, sensors, and pumps are the components that keep oil moving, monitor engine conditions, and prevent leaks. A failing seal lets oil escape and contaminates the engine. A bad sensor sends wrong readings that throw off fuel mixture and timing. A weak pump can't deliver oil pressure where it's needed. Understanding what these parts do and how to spot trouble helps you catch problems before they damage the engine.
The articles here explain how each component works, what symptoms point to failure, and what happens when you ignore the warning signs. You'll learn which seals fail most often, how sensors communicate with your engine computer, and why oil pump pressure matters for engine longevity.
