During cylinder head inspection, what should be examined?

• A. Wiring harness for wear and securement
• B. Intake manifold gasket
• C. Turbocharger compressor
• D. Exhaust pipe hangers

Answer: (A)

Focus on the wiring harness around the cylinder head. The head area hosts many electrical connections to sensors, injectors, and ignition components, and the harness must be intact and properly secured to avoid exposure to heat, rubbing, or movement. Damaged or loose wiring can cause misfires, sensor faults, or starting issues, which are directly tied to how the head and its attached systems operate.

The intake manifold gasket, while related to the head region, is a sealing component rather than a primary inspection item for the cylinder head itself. The turbocharger compressor and exhaust pipe hangers are part of other systems (turbocharging and exhaust) and aren’t core to inspecting the cylinder head’s condition.
