Sump Plate Appraisal

Dry Sump Oil Pump Plate Assembly (likely ZPE/PZ)

The item appears to be an automotive component, likely a dry-sump oil pump or a similar oil management system part, intended for high-performance applications. It predominantly consists of a precision-machined aluminum plate with a bright, satin-like finish, indicating it could be CNC-milled from billet aluminum. The plate is irregularly shaped with multiple drilled and tapped holes of various sizes along its perimeter and interior, suggesting it fastens to another engine component and allows for fluid passages or component mounting. Two notable brass-colored bushings are pressed into circular openings on the main plate, which are likely bearing surfaces for shafts or gears, suggesting precision movement. Visible components attached to or extending from the main plate include a cylindrical shaft, partly encased in clear plastic packaging, featuring what looks like a gear or a cam at one end. Another smaller, intricately machined metal component with multiple orifices is visible, likely a valve body or manifold. The overall construction quality appears to be high, with clean lines and smooth surfaces, typical of performance automotive parts where tolerances and material strength are critical. There are no obvious signs of wear, damage, or repairs; the item appears to be new or unused, still within its original, albeit opened, cardboard packaging. The design suggests a modern manufacturing process, likely from the late 20th or early 21st century. The brand 'ZPE' or 'PZ' is subtly embossed or etched into the metal of the main plate near one of the circular openings, indicating the manufacturer.
