DJ Rock OP670 Engine Oil Pump

Engine Oil Pump for Nissan and Infiniti

The DJ Rock OP670 engine oil pump maintains pressurized oil circulation through the engine to protect rotating and sliding components from friction and heat. Built with a cast aluminum housing, rotary pump design, and standard pressure output, it is a direct-fit lubrication component for select Nissan and Infiniti applications.

Compatible With 1991-1996 Infiniti G20, 1991-1994 Nissan Sentra, 1995-1998 Nissan 200SX, 1991-1993 Nissan NX, and 1998-1999 Nissan Sentra. The OP670 is also cross-referenced to 028-0360, M382, and PD30 for the same application.

Key Features

• Premium-grade engine oil pump for crankshaft-driven lubrication systems
• Cast aluminum housing for strength and resistance to warping
• Rotary oil pump design with standard pressure and standard volume output
• Pressure relief valve helps regulate oil pressure during cold starts and higher engine speeds
• Gasket or seal included for installation
• 12 mounting holes for OE-style fitment

Detailed Description

DJ Rock OP670 is an engine oil pump engineered to circulate oil under pressure so critical engine parts receive consistent lubrication. The rotary design uses internal rotors to move oil efficiently, while the pressure relief valve helps control system pressure under changing operating conditions. Its cast aluminum housing supports durability in high-temperature engine environments, and the crankshaft drive type matches the listed vehicle applications. This part number, OP670, is built for drivers servicing Nissan Sentra, Nissan 200SX, Nissan NX, and Infiniti G20 engines that require a standard-pressure, standard-volume oil pump.

What It Helps Fix

• Low oil pressure caused by a worn or failing pump
• Oil circulation problems that can lead to increased engine wear
• Pressure fluctuations during cold starts or high-RPM operation
• Noise or damage related to inadequate lubrication
• Engine rebuild service where the original pump no longer meets specification

Installation Notes and Tips

Verify engine code, mounting pattern, and pump drive style before installation. Clean the oil passages, inspect the pickup and related lubrication components, and prime the pump before startup to establish oil flow quickly. Because the OP670 uses a crankshaft drive and 12 mounting holes, confirm alignment and gasket sealing surfaces during assembly. For Nissan Sentra and Infiniti G20 applications, match the pump to the exact model year listed in the fitment data.

Quality Assurance

DNJ oil pumps are manufactured to meet or exceed OEM quality standards and use durable materials selected for long service life under demanding engine conditions. The OP670 follows that approach with a precision rotary design, cast aluminum housing, and pressure control components built for reliable lubrication performance.
