Question: 1 / 400

Which part of the engine must be removed before the push rods can be removed?

camshaft

flywheel

oil pan

rocker arms

Before the push rods can be removed, the rocker arms must be removed first. Rocker arms are responsible for transferring the camshaft action to the valves, and they sit on top of the cylinder head. By removing the rocker arms, the push rods, which transfer motion from the camshaft to the rocker arms, can then be accessed and removed.

Option A (camshaft) is incorrect because the camshaft is not directly blocking access to the push rods; it is responsible for controlling the opening and closing of the engine's valves.

Option B (flywheel) is incorrect because the flywheel is connected to the crankshaft and is part of the engine's ignition system, but it does not need to be removed to access the push rods.

Option C (oil pan) is incorrect because the oil pan is located beneath the engine and is responsible for holding the engine's oil, it does not need to be removed to access the push rods.
