Engine Oil Pump

The DNJ Engine Components OP290 is an engine oil pump engineered to circulate oil under pressure, crucial for lubricating rotating and sliding engine parts. Each pump assembly includes a housing, internal rotors or gears, and a pressure relief valve to regulate oil pressure under varying operating conditions. Constructed for durability and precision, the DNJ OP290 features a robust housing made from either cast aluminum or cast iron, offering resistance to warping and corrosion even under extreme engine temperatures. Internally, high-strength gears or rotors crafted from hardened steel ensure long-lasting wear resistance and maintain the tight tolerances required for efficient oil circulation. The unit also incorporates a pressure relief valve with a steel spring and plunger assembly to manage system pressure and protect the engine during cold starts or high-speed operation. Manufactured to meet or exceed OEM quality standards, this DNJ oil pump is built to deliver reliable performance. It is compatible with 1988-1995 Honda Civic, 1988-1991 Honda CRX, and 1993-1995 Honda Civic del Sol models. DNJ Engine Components also provides a full range of related lubrication system parts to support engine rebuilds.
