the EGR valve is used to connect the exhaust manifold and the intake manifold. This valve is generally closed, so there is no EGR flow whenever the engine is cold, inactive, or through hard acceleration. In steady cruising, the flow of EGR is at its peak in moderate...
You will also hear some light pooping noises that follow the bad engine performance. This phenomenon is called ‘backfiring’ and is a common sign of a leaky gasket.Leaking of coolantAs the intake manifold gasket transports both the air-fuel mixture and coolant, a crack in it means you are...
