MPZ Engine Assembly Lube HP Case/12-5oz Tube

The MPZ Engine Assembly Lube HP Case/12-5oz Tube is a specialized pre-assembly lubricant designed for high-performance engine builds and rebuilds. This product is ideal for mechanics and engine enthusiasts preparing a fresh block for break-in, as it protects critical internal surfaces during initial startup and assembly.

Engine assembly lubes create a protective boundary layer on cam lobes, valve lifters, and bearing journals—surfaces that often experience oil starvation during the first moments after cold ignition. The MPZ formulation includes extreme-pressure additives and high zinc (ZDDP) content, ensuring effective boundary lubrication before conventional oil film is established. Its thick, tacky consistency clings to vertical valve train components, providing anti-wear protection during the critical pre-oiling phase.

This assembly lube is essential for any engine rebuild, offering concentrated protection without dilution. Each case contains 12 individual 5-ounce tubes, making it suitable for multiple engine builds or professional shop inventory. Apply directly to cam lobes, rocker arms, and bearing surfaces before final assembly and piston installation for optimal results.
