🔍 Key Concepts

• Study the rocker arm and what components it directly contacts at each end. • Look closely at the valve area to see whether there is a separate valve bridge connecting two valve stems, or individual valves operated separately. • Examine the cylinder liner and water passages to decide whether this is a wet or dry liner design.

💭 Think About

• From the illustration alone, can you see any part that would allow one rocker to push on two separate valve stems at the same time? What would that part look like? • Where is the engine coolant (blue areas) located in relation to the liner wall? Does the liner seem to be in direct contact with coolant, or is there a solid block between them? • If an intake valve needed clearance (lash) for thermal expansion, where in this mechanism would that adjustment be made, and do you see such an adjusting feature in the drawing?

✅ Before You Answer

• Identify whether a valve bridge is actually drawn between two valves, or if each valve stem stands alone. • Confirm whether coolant passages appear directly against the liner (typical wet liner) or separated by block material (typical dry liner). • Locate any adjusting screw or nut in the rocker/pushrod/valve train that would allow setting intake valve clearance.

Intake and exhaust valves open simultaneously.

The rocker arm causes a valve bridge to open the valves simultaneously.

The illustrated engine utilizes a dry type cylinder liner.

The intake valve requires no adjustment.
