Standard Ignition EGV364 Exhaust Gas Recirculation (EGR) Valve

Standard Ignition EGV364 EGR Valve

Standard Ignition EGV364 is a mechanical exhaust gas recirculation (EGR) valve built for direct replacement on select GM applications. It uses stainless steel valve components for durability and a polyester-reinforced silicone diaphragm that resists thermal aging at temperatures up to 200degC.

Compatible With 1984-1985 Buick Century, 1986-1987 Buick Regal, and 1986 Buick LeSabre applications, this EGR valve supports emissions system service where precise exhaust gas recirculation control is required. The EGV364 part number is also referenced for additional Buick, Oldsmobile, and Pontiac applications.

• Mechanical EGR valve with no connector
• Stainless steel valve components for long-term durability
• Polyester-reinforced silicone diaphragm for heat resistance
• Reinforced gasket included for complete replacement
• One hose connector

Detailed Product Overview

Standard Ignition EGV364 is an emission control replacement part for vehicles that use a mechanical EGR valve design. It is built with corrosion-resistant stainless steel internal components and a reinforced silicone diaphragm to maintain performance under elevated exhaust temperatures. The included gasket supports a proper seal during service, helping restore the EGR system to factory-style operation on applications such as the Pontiac Firebird, Oldsmobile Delta 88, and Buick Skylark.

This part cross-references Gates 41138 for the same application.

Common Issues This Part Addresses

• EGR valve sticking open or closed
• Rough idle caused by improper exhaust gas recirculation
• Emissions-related fault conditions tied to EGR flow
• Vacuum or diaphragm failure in a mechanical EGR valve
• Exhaust gas recirculation leaks at the mounting surface

Installation Notes and Tips

Verify the vehicle uses a mechanical EGR valve with no electrical connector before installation. Inspect the mounting surface and vacuum hose connection, and replace any damaged hose or carbon-fouled passage during service. Use the included gasket to ensure a complete seal, and confirm the valve matches the original configuration for the specific Buick, Oldsmobile, or Pontiac application.

Quality Assurance

Standard Ignition maintains quality control throughout the manufacturing process, from component selection to finished product. The EGV364 is built to meet the demands of emissions system service with durable materials and controlled assembly standards.
