DJ Rock OP951 Engine Oil Pump

Engine Oil Pump Overview

This engine oil pump is built for applications that require steady oil circulation and pressure control inside the engine. It fits a range of Toyota, Pontiac, and Chevrolet applications, including Toyota Corolla, Toyota Matrix, and Pontiac Vibe fitments, with part number OP951 used for direct catalog matching.

• Rotary oil pump design for consistent oil delivery.
• Aluminum housing for strength and corrosion resistance.
• Standard pressure and standard volume configuration.
• Includes gasket or seal for service-ready installation.
• Crankshaft-driven operation for engine lubrication systems.

How It Works

OP951 circulates oil under pressure to lubricate rotating and sliding engine components, helping maintain oil flow during cold starts and higher-speed operation. The rotary design, aluminum housing, and pressure relief control support stable lubrication performance in engines that depend on accurate oil delivery. This part number, OP951, is listed for multiple Toyota Corolla and Toyota Matrix applications, along with Pontiac Vibe and Chevrolet Prizm fitments.

Common Problems It Addresses

• Low oil pressure caused by pump wear.
• Inconsistent lubrication from weakened internal components.
• Engine friction from reduced oil circulation.
• Overheating related to poor oil flow.
• Pressure spikes during variable operating conditions.

Installation Notes

Verify engine application, drive type, and mounting-hole layout before installation. This pump uses a crankshaft drive and a rotary design, so matching the engine configuration is essential. Confirm gasket or seal requirements during service and inspect the lubrication system for contamination or wear that could affect pump performance.
