🔍 Key Concepts

• Look closely at the valve springs on the exhaust valve to see if there is one spring or a nested inner and outer spring. • Trace how valve lash (clearance) would actually be adjusted in this layout – is the adjustment at the rocker arm or on the push rod? • Examine the top of the two exhaust valves and rocker area to see whether there is a valve bridge connecting both valves, and how they are actuated and cooled.

💭 Think About

• For each choice, ask yourself: "Can I physically see this feature in the drawing, or is it clearly NOT present?" and eliminate the choices that don’t match the illustration. • Imagine the motion path: cam → push rod → rocker (or bridge) → valve stem. Which option best matches the way these parts are drawn and connected? • Where would cooling oil need to flow if the exhaust valves were oil cooled, and is any such passage or connection actually indicated in the figure?

✅ Before You Answer

• Carefully count how many springs are on each valve and whether they are concentric (one inside another). • Identify the exact location of the adjusting screw and locknut for valve clearance – note which component they are mounted on. • Verify whether there is a single valve stem directly under the rocker, or a bridge piece that would allow one rocker to open two valves at the same time.

Both exhaust valves are oil cooled.

Dual sets of valve springs are used for each valve to reduce valve bounce.

Valve lash is mechanically adjusted at the top end of the push rod.

Both exhaust valves are opened simultaneously by the valve bridge.
