🔍 Key Concepts

• thermal expansion of metal parts as an engine warms up • the purpose of valve clearance (lash) in an internal combustion engine • which components are designed to compensate for changes in length of the valve train

💭 Think About

• When metal heats up, it expands. Which part of the valve train is specifically intended to make sure the valves still open and close correctly as this happens? • Think about the normal function of each option: which one directly relates to the movement and clearance of valves, rather than speed control or cooling? • Which component’s job is to maintain the correct clearance between the cam and the valve stem as temperatures change?

✅ Before You Answer

• Eliminate any option whose main job is engine speed control rather than valve operation. • Eliminate any option whose main job is removing heat from the engine rather than managing clearance. • Focus on the component that directly affects valve clearance/lash as parts expand with temperature.
