I think we have all seen the examples, and in some cases experienced the effects of EGR valve contamination, including soot build-up into the EGR inlet manifold circuit and even post EGR valve.
Now the EGR route will be rich with carbon/soot but what interests me is how contaminated the whole engine inlet manifold and valve ports get?
Main air intake is off course via the normal air filter induction route but how contaminating is the EGR circuit creating in the inlet tract / chamber and this should be a concern?
Has anybody stripped down a modern turbo diesel with EGR recurcutlaion and can comment on relative EGR circuit crud compared to inlet crud build-up.
