Standard Ignition EGV354 EGR Valve

Standard Ignition EGV354 EGR Valve for Oldsmobile

The Standard Ignition EGV354 is a mechanical exhaust gas recirculation valve built for direct replacement service on select 1973-1974 Oldsmobile applications. It uses stainless steel valve components, a polyester-reinforced silicone diaphragm rated for thermal aging resistance up to 200°C, and a reinforced gasket for a complete replacement.

Key Features

• Mechanical EGR valve design
• Stainless steel valve components for durability
• Polyester-reinforced silicone diaphragm resists heat-related aging
• Diaphragm material is rated for temperatures up to 200°C
• Reinforced gasket included
• 1 hose connector and 2 bolt holes

Detailed Description

Standard Ignition EGV354 is an exhaust gas recirculation valve for emission control service on 1973-1974 Oldsmobile 98, Custom Cruiser, Cutlass, Delta 88, Omega, and Toronado models. This EGR valve is built with mechanical operation and durable internal materials to support consistent exhaust gas recirculation function in the vehicle’s emission system. The included gasket helps complete the replacement, and the 1-hose, 2-bolt design supports straightforward OE-style service. This part number, EGV354, is also a useful reference when matching the correct replacement for Oldsmobile EGR valve applications.

This part cross-references Karlyn 30365 for the same application.

What It Helps Address

• Rough idle caused by an EGR valve that is sticking open or closed
• Emission system faults related to exhaust gas recirculation flow
• Driveability issues tied to improper exhaust gas recirculation operation
• Vacuum-related EGR concerns on mechanical valve systems
• Replacement needs for aging EGR components on 1973-1974 Oldsmobile models

Installation Notes and Tips

Verify the vehicle’s original EGR valve style, hose connection layout, and bolt-hole pattern before installation. Confirm fitment for your specific Oldsmobile 98, Custom Cruiser, Cutlass, Delta 88, Omega, or Toronado application, since EGR components must match the original emission system configuration. Use the included gasket during installation and inspect the mating surfaces for carbon buildup or damage before mounting the new valve.

Quality Assurance

Standard Ignition manufactures emission components with quality control maintained throughout the process, from individual components to the finished valve. The EGV354 is built with durable materials selected for heat resistance and long-term service in emission control applications.
