Art style: манга 4.
Tampilan dekat piston mesin yang mengkilap dan kepala silinder yang baru dibersihkan, diletakkan dengan rapi di atas tumpukan koran Jepang yang sudah menguning. Tetesan oli baru berwarna keemasan terlihat di permukaan logam. Cahaya samping yang dramatis menonjolkan tekstur logam dan detail teknis komponen mesin tersebut.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "манга 4" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "манга 4".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "манга 4" idiom, not in any other medium.
