DPTOOL Oil Pump Primer Tool for GM Chevy V6 & V8 SBC 350/454 – Pre-Start Oil Pressure Prime

Prime Your Engine Before Start

The DPTOOL Oil Pump Primer Tool is built to help you prime your engine before the first crank. By attaching to a drill motor, it spins the oil pump so oil moves quickly to the top end, priming galleries and components ahead of time. This approach may reduce dry-start wear and give you a smoother initial rotation.

Why choose this tool

• Faster oil pressure build before first startup, supporting prompt lubrication of critical components.
• Improved top-end lubrication of the camshaft, lifters, and valve train for a potentially smoother idle and startup.
• Potentially reduced startup wear by circulating oil earlier in the process.
• Versatile fitment across GM small- and big-block Chevy engines and multiple block sizes.
• Works with common drill chucks (3/8" or 1/2"), enabling easy setup on many benches.

Engine compatibility and build quality

• Fits SB/BB Chevy V8 & Chevy V6 engines, covering popular platforms from street builds to performance projects.
• Compatible with common block sizes including 327, 350, 355, 383, 388, 400, 406, 427, 434, and 454.
• Featuring a billet aluminum sleeve that precisely positions the shaft and keeps it from wobbling during use.
• Thick shaft design with a triangle-shaped end to prevent slippage while priming.
• Designed for 3/8" or 1/2" drill chucks, making it easy to integrate with standard drill setups.

Real-world scenarios include engine builds, rebuilds, or tuning sessions where you want to ensure oil is circulating before ignition. While results can vary by engine and setup, the tool offers a straightforward method to help move oil through the system and lubricate critical parts prior to starting.

Usage snapshot

• Attach to the drill and connect to the engine’s oil pump inlet.
• Slide the billet sleeve into precise alignment, then run the drill to prime.
• Disconnect, re-torque as needed, and proceed with normal startup procedures.
