Oil Pump - AMC 6-Cylinder

The Oil Pump - AMC 6-Cylinder by MELLING (model M167HVS) is a direct-replacement lubrication component engineered for classic and vintage AMC six-cylinder engines. Whether you're restoring a Rambler, Javelin, or Gremlin, or maintaining original equipment in daily-driven muscle cars, this pump is essential for sustained engine health and reliable oil delivery. As a mechanic, you know that oil circulation is non-negotiable—inadequate flow leads to bearing wear, cam lobe damage, and catastrophic engine failure within hours of running.

MELLING's design delivers consistent pressure and flow rate across the full operating temperature range, using a gear-driven mechanism that synchronizes with crankshaft rotation for reliable priming and circulation. The cast iron construction and precision-engineered internal geometry ensure longevity under both stock and mildly modified engine builds. At 5.23 lbs and measuring 5.5 × 4.1 × 13.6 inches, this pump integrates seamlessly into OEM mounting locations, requiring no adapter modifications or custom fabrication. The M167HVS designation confirms compatibility with AMC's classic six-cylinder block architecture, making it the correct choice for period-correct restoration or straightforward replacement maintenance.

Rebuild shops and individual enthusiasts benefit from MELLING's reputation for durability and tight tolerances—this pump won't rob horsepower or generate excessive noise like worn OEM units. Installation is straightforward: simply bolt it to the engine block using existing fastener holes, verify timing alignment with the crankshaft, and prime the system before start-up to avoid dry running. For anyone rebuilding a 258, 232, or 199 cubic-inch AMC engine, this Oil Pump - AMC 6-Cylinder is the trusted, drop-in solution that restores proper lubrication flow and extends engine life.
