The exhaust gas recycle (EGR) system is designed to help prevent detonation or spark knock. When these conditions are allowed to continue, they can drastically raise the temperature and pressure in the combustion chamber. This can have the effect of blowing head gaskets and damaging internal engine components. For more information on valve clatter see our article Valve Clatter, Spark Knock, Pinging and Pre-ignition.
