Interactive 3D V8 Engine Animation

Build me a V8 car engine in interactive 3D, in one HTML file with Three.js.

Make it look real: the engine block with its two banks of cylinders in a V, the pistons and connecting rods, the crankshaft, the camshafts and valves on top, the intake manifold and the exhaust headers glowing hot. The pistons pump up and down, the crankshaft turns, and the spark plugs flash when each cylinder fires. I can drag to orbit around it and scroll to zoom.

Add an Explode button. When I press it, every part slides apart with its name on a label. Press it again and it all snaps back together. When I hover a part, it lights up and shows one line on what it does.

No images. Do not ask me any questions. Just build it.
