As a broad statement this is probably true for things such as valves, but for the intake manifold and intake runners EGR is the primary source of CBU, otherwise, there is nowhere for partially oxidized carbon to come from but from the EGR. And as we are having a problem with the build up in the intake manifold and head runners, eliminating the EGR will solve the problem.
