Where does the EGR valve connect to the intake manifold?
Note where the EGR Valve connects to the intake manifold or cylinder head. This is where the largest amount of carbon will be built up due to the change in temperature as the hot exhaust gases come into contact with the cool intake manifold gases. This will be where you start the EGR passage cleaning procedure.
