Which items should be inspected as part of the engine block inspection?

• A. Pans, gaskets, and ventilation components
• B. Fuel injectors
• C. Radiator core
• D. Cylinder sleeves

Answer: (A)

Engine block inspection focuses on components that seal, contain oil, and regulate crankcase ventilation. The oil pan sits at the bottom of the engine and must be checked for cracks, warping, and leaks; its gasket must seal properly to prevent oil loss and contamination. Gaskets between major joints—oil pan, cylinder head, and valve covers—need to be intact, since a failed gasket can allow oil or coolant to escape and harm the engine. The ventilation system, including the PCV valve and associated hoses, must function to maintain correct crankcase pressure and remove blow-by gases; if this path is blocked or damaged, oil leaks and pressure problems can occur, affecting engine health.

Fuel injectors belong to the fuel system and are not part of the engine block’s basic inspection, while the radiator core is part of the cooling system, and cylinder sleeves are internal components that aren’t typically the focus of a standard engine block inspection.
