Chevy Oil Pump Primer

The Chevy Oil Pump Primer by MILODON is an essential tool for any mechanic or performance enthusiast working on Chevrolet small block and big block engines. This specialized priming tool eliminates the risk of running an engine dry during initial startup by pre-lubricating the oil pump, galleries, and bearing surfaces before ignition. Whether you're installing a fresh crate motor or rebuilding a classic Chevy block, this primer ensures critical oil pressure is established instantly, preventing catastrophic bearing damage.

MILODON's oil pump primer features a compact, durable design that threads directly into the oil filter mounting pad or designated priming port on Chevy block assemblies. The tool operates by manually rotating the drive shaft to mechanically cycle the oil pump without engine combustion, forcing fresh oil through the entire lubrication system. This method is far superior to simply cranking the engine with the ignition disabled, as it guarantees oil reaches critical zones like valve lifters, rocker arms, and crankshaft journals.

Professional engine builders and restoration shops will benefit most from this tool, as it provides peace of mind during engine assembly and ensures optimal lubrication from the start. The lightweight construction (0.85 lbs) and compact dimensions (2 x 1.7 x 9.3 inches) make it portable and easy to handle in tight engine bays or on the workbench. This oil pump primer is a must-have for anyone looking to protect their investment in engine performance.
