Oil Pan — The main oil reservoir for the WP12 engine, constructed from heavy-gauge steel with a corrosion-resistant coating. This pan includes integrated baffles to control oil slosh during acceleration, braking, and cornering, ensuring a steady supply of oil to the pump pickup. The deep sump design increases oil capacity, improving cooling and dilution resistance, while the precision-formed sealing flange accepts a gasket for a leak-proof fit to the cylinder block. The pan is also engineered to withstand high-temperature and high-vibration environments, providing long-term structural integrity.

Assembled Sealing Washer — A pre-assembled sealing washer that combines a metal retainer with an elastomeric sealing element. Specifically designed for the oil drain plug, this washer provides a reliable, leak-free seal between the plug and the oil pan. The metal retainer ensures consistent compression, while the elastomer conforms to the mating surfaces, preventing oil seepage even under extreme thermal cycling and vibration. This component is critical for maintaining oil integrity and preventing environmental contamination.

Oil Drain Screw Plug — A robust threaded plug used to seal the oil drain hole in the oil pan. Manufactured from high-strength steel with a corrosion-resistant finish, this plug features a hexagonal head for easy removal and installation with standard tools. The precision-cut threads ensure a tight fit, while the integrated sealing washer (often included) guarantees a leak-proof seal during normal engine operation. This component is designed for repeated removal and installation without compromising its sealing ability, making oil changes simple and reliable.
