Visual Inspection of Engine Bay

What happens here

The presenter opens the truck's hood to inspect the engine bay. He visually checks all connections to the coil packs and fuel injectors on both sides of the V8 engine, confirming they are securely attached. He points out that the truck is equipped with a Vortec 6.0L engine. He briefly mentions the factory coil packs and spark plugs, noting they appear to be original and there are eight coil packs (one per cylinder). During the visual inspection, he discovers foam and a small amount of oil near one of the rear coil packs, and also observes a significant antifreeze leak from a heater hose onto wires and a coil pack, which he suspects might be the root cause of the misfire.

Goal: Visually inspect ignition components and identify any obvious issues.
