Each IAG Stage 1 Blueprinted EJ25 11mm Oil Pump begins as a new OEM Subaru oil pump equipped with 11mm rotors. IAG's skilled technicians disassemble it, carefully checking for contaminants and debris left by the manufacturer. Ultrasonic cleaning ensures a pristine foundation for the modification process. One key enhancement is the REM polishing of the OEM Pressure Relief Valve Piston, creating a low Ra surface. This significantly reduces friction, minimizing the risk of piston galling or sticking in the bore, which is a common problem even with brand new oil pumps. IAG reinstalls and validates the piston's correct operation for added peace of mind. The rotor measurements are meticulously checked against the manufacturer's specifications, ensuring precision and consistency. This attention to detail is part of IAG's blueprinting process, guaranteeing a high-quality product. The pump is then expertly reassembled using assembly lube to reduce friction and scuffing while facilitating priming during the initial startup. To complete the package, the backing plate is installed with hardware secured using Loctite for added reliability. To ensure quality control, each torqued piece receives a painted mark, indicating its correct installation.
