Identify and describe the main visible components of the engine in the image.

Here are the key components visible in the image: • Engine Block: This is the main structural component of the engine, housing the cylinders and providing mounting points for other parts. • Cylinders: The four circular openings within the engine block where the pistons move. This appears to be a 4-cylinder engine. • Pistons: Visible inside the cylinders, these components move up and down to compress the air-fuel mixture and transmit power from combustion. • Cylinder Head Gasket: A crucial sealing component placed on top of the engine block. It ensures a tight seal between the engine block and the cylinder head (which is not yet installed), preventing leaks of combustion gases, coolant, and oil. • Exhaust Manifold: A rusty, cast-iron component visible on the right side of the engine block. It collects exhaust gases from the cylinders and directs them out of the engine. • Wiring Harnesses and Hoses: Numerous electrical wires and rubber hoses are visible throughout the engine bay, connecting various sensors, actuators, and fluid systems. 3 done, 2 left today.
