2000 Chevrolet Blazer - EGR Valve Gasket

EGR Valve Gasket Replacements

The EGR (exhaust gas recirculation) valve gasket is a seal between the EGR valve and the engine block or intake manifold, and provides a leak-free connection between these components to prevent exhaust leaks. The EGR system is designed to cycle a portion of the exhaust gasses back into the cylinders, which reduces emissions and lowers the combustion temperature inside the cylinders - this can also increase your engine's efficiency. Just like any other gasket, the EGR valve gasket can wear out over time. This may lead to leaks that can cause issues with the EGR system's functioning and engine performance. Symptoms of a bad or failing EGR valve gasket might include poor engine performance, misfires, increased emissions, and in some cases, a noticeable exhaust smell under the hood or in the cabin. If your vehicle is experiencing power loss, rough idle, or an illuminated Check Engine light, inspect the EGR valve and gasket for any damage. Your local O'Reilly location can also scan your Check Engine codes for free to see if the issues you are experiencing may be attributed to an EGR valve or EGR gasket failure.
