An overhead view captures the exposed valvetrain of an internal combustion engine, likely within an engine bay in Karu, Nigeria. The valve cover has been removed, revealing two overhead camshafts coated in dark engine oil. Multiple camshaft bearing caps secure the shafts in place with visible bolts. Three cylindrical spark plug tube housings are positioned vertically between the camshafts, also showing oil residue. A large camshaft gear is present on the left end of the front camshaft, and a smaller gear on the right end of the rear camshaft. The exposed interior surfaces are heavily lubricated with dark, viscous oil, some areas exhibiting sludge buildup. To the immediate left of the exposed valvetrain, a metallic component with four oval-shaped ports, possibly an intake manifold gasket surface or a removed manifold itself, lies detached. Various hoses, wires, and connectors are visible around the engine components. To the right, a rusty, yellowish-brown metallic manifold structure is present, with the yellow loop of a dipstick handle visible at the bottom right. A blurred human arm or hand is partially visible in the upper background, suggesting ongoing work or inspection of the engine. The overall scene indicates engine maintenance or repair.
