Q

If the intake, or exhaust valve stem clearance is found to be excessive, in addition to too little movement of the rocker arms, you should check for __________.

🔍 Key Concepts

• Valve train components involved in opening/closing valves (rocker arms, pushrods, lifters, springs, locks, seats) • How hydraulic valve lifters work to maintain zero clearance • What condition would cause both excessive stem clearance AND reduced rocker arm movement

💭 Think About

• Think about which component, if it failed, would reduce how far the cam’s motion is transmitted up to the rocker arm. • Ask yourself: which option would mainly affect valve seating and sealing, but not necessarily rocker arm travel? • Consider which parts are designed to automatically take up clearance, and what happens when they no longer can do that.

✅ Before You Answer

• Match the symptom: excessive valve stem clearance + too little rocker arm movement to the component that transfers motion from cam to rocker. • Eliminate choices that mainly affect valve seating or spring tension but not the amount of rocker arm travel. • Verify which part is specifically designed to keep proper lash (clearance) without regular adjustment.
