🔍 Key Concepts

• Identify which components normally form the valve lash (tappet clearance) surface in an overhead valve system • Recall where the feeler gauge is inserted when checking cold valve clearance on a rocker-arm type valve train • Determine which point in the rocker mechanism is used for mechanical adjustment (locknut/adjusting screw) rather than for measurement

💭 Think About

• Look carefully at the labeled points A, B, C, D, and E and decide which pair actually separates when the valve is fully closed and the pushrod is on the cam’s base circle • Ask yourself: where would a mechanic realistically slip a flat feeler gauge blade in this layout—between the rocker and the valve stem tip, or somewhere on the pushrod side? • Which labeled point clearly shows an adjusting screw and locknut arrangement, and which labeled point is simply a contact surface?

✅ Before You Answer

• Verify which surfaces are the rocker arm-to-valve stem contact, as this is the typical location for measuring valve lash on this style of engine • Confirm which labeled point represents the adjusting screw/locknut used to change that clearance mechanically • Eliminate any option that suggests measuring clearance where there is no sliding contact surface suitable for a feeler gauge
