Standard Ignition EGV341 EGR Valve

Standard Ignition EGR Valve EGV341

Standard Ignition EGV341 is a mechanical exhaust gas recirculation valve built for emission-control service on select Chevrolet, GMC, Buick, Oldsmobile, and Pontiac applications. It uses stainless steel valve components and a polyester-reinforced silicone diaphragm to handle heat and long-term operation in demanding engine bay conditions.

With confirmed fitment for 1977-1984 vehicles, this EGR valve is a direct replacement choice for owners servicing emissions-related drivability concerns on classic GM platforms, including 1984 Chevrolet G10 and 1977 Pontiac Firebird applications.

Key Features

• Mechanical EGR valve design
• Stainless steel valve components for durability
• Polyester-reinforced silicone diaphragm resists thermal aging up to 200degC
• Reinforced gasket included for complete replacement
• 1 hose connector and 2 bolt holes
• Standard Ignition part number EGV341

Detailed Description

Standard Ignition EGV341 is an exhaust gas recirculation valve for emission control systems that require a mechanical valve layout. The stainless steel internal components are selected for durability, while the reinforced silicone diaphragm is built to withstand elevated operating temperatures. The included gasket helps support a proper seal during replacement, which is important for maintaining stable EGR operation and reducing exhaust leakage at the mounting surface. This part cross-references 17054785 and EGR129 for the same application.

Compatible With select 1977 Buick Century, LeSabre, Regal, Riviera, and Skylark applications; 1977 Oldsmobile 98, Cutlass, Delta 88, Omega, and Toronado applications; 1977 Pontiac Bonneville, Catalina, Firebird, Grand LeMans, Grand Prix, LeMans, and Phoenix applications; 1978 Oldsmobile Toronado; and 1984 Chevrolet G10, G20, G30 and GMC G1500, G2500, G3500 vans with the listed emissions and axle-ratio notes.

What It Helps Address

• EGR valve sticking or improper valve movement
• Emissions-related fault conditions tied to exhaust gas recirculation flow
• Rough idle or drivability issues associated with EGR malfunction
• Vacuum or sealing concerns at the EGR mounting point
• Replacement needs on aging GM emission-control systems

Installation Notes and Tips

Verify the vehicle’s emissions configuration, OE number, and mounting style before ordering. This EGR valve uses a mechanical design with one hose connector and two bolt holes, so confirm the existing routing and flange pattern match the application. Clean the mounting surface thoroughly before installation and inspect the vacuum line and adjacent emission components for wear or cracking.

Quality Assurance

Standard Ignition states that quality control is maintained throughout the manufacturing process, from component selection through finished product inspection. The EGV341 is built with durable valve materials and a reinforced gasket to support a complete replacement on the specified applications.
