It seems like you're looking for an overview of the oil system in an internal combustion engine. Let’s clarify how these components interact with motor oil:

  1. The Camshaft and Lifters: The camshaft is responsible for opening and closing the engine’s valves, and it relies on proper lubrication to function effectively. Motor oil circulates through the engine and lubricates the camshaft and lifters (also known as tappets), reducing friction, preventing wear, and helping to dissipate heat.

  2. Anything in the Engine that Motor Oil Touches: This includes various components like bearings, the crankshaft, oil pump, and other moving parts. Motor oil is crucial for lubrication, reducing wear, and cleaning the engine by carrying away contaminants. It creates a protective film on metal surfaces, allowing for smoother operation.

  3. The Pistons and Chambers: Pistons move up and down in the cylinders, creating the necessary compression for combustion. Oil forms a thin film between the piston and cylinder walls, sealing in the combustion gases and preventing metal-to-metal contact. It also helps to cool the pistons and control engine temperature.

  4. The Dipstick: While it does not directly involve the oil system's functionality, the dipstick is an important tool for monitoring the oil level and condition. It provides a way to check whether there is enough oil in the engine and helps identify if the oil needs to be changed.

Together, these components create an efficient oil system that is vital for the engine's performance and longevity. Regular maintenance, including oil changes and level checks, is essential to keep the oil system functioning optimally.

Pick one answer

The oil system in an engine primarily involves anything in the engine that motor oil touches. This encompasses all components that require lubrication to operate smoothly and efficiently, including camshafts, lifters, bearings, and pistons.
